steel plate

  What types of steel plates are there? Please see: Complete list of steel plate models!      Steel plate is one of the four major varieties of steel (plate, pipe, type, and wire). In developed countries, the output of steel plate accounts for more than 50% of the total steel production. With the development of my country's national economy, the production of steel plate is gradually increasing.    A steel plate is a flat steel material with a large aspect ratio and surface area. Steel plates are divided into two specifications: thin plate and thick plate according to their thickness.    Thin steel plate is a steel plate with a thickness between 0.2-4mm produced by hot rolling or cold rolling. The width of the thin steel plate is between 500-1400mm. According to different purposes, thin steel plates are rolled from billets of different materials. Commonly used materials include ordinary carbon steel, high-quality carbon steel, alloy structural steel, carbon tool steel, stainless st

  How to distinguish the steel plate material is Q235 and Q345?       The appearance of Q235 and Q345 is generally invisible. The color difference has nothing to do with the material of the steel, but is caused by the different cooling methods after the steel is rolled out. Generally, the surface is red after natural cooling. If a rapid cooling method is used, a dense oxide layer is formed on the surface, and it will appear black.       Generally, Q345 is used in strength design, because Q345 is stronger than Q235 steel, saving steel, 15%-20% less than 235. It is better to use Q235 when designing with stability control. The price difference is 3%---8%.       As for identification, there are several theories:      A:     1. In the factory, the method of trial welding can be used to roughly distinguish the two materials. For example, use E43 welding rods to weld a small round steel on two steel plates, and then apply shear force, and roughly distinguish the materials of the two steel pla

 The difference between Q235 hot-rolled steel plate and cold-rolled steel plate         The hot-rolled sheet has low hardness, easy processing and good ductility. Cold-rolled sheet has high hardness and is relatively difficult to process, but it is not easy to deform and has high strength. The strength of the hot-rolled sheet is relatively low, and the surface quality is poor (with low oxidation finish), but the plasticity is good, and it is generally a medium-thick plate. The cold-rolled sheet: high strength, high hardness, and high surface finish. .      The mechanical properties of hot-rolled steel sheets are far inferior to those of cold-worked and forged, but they have better toughness and ductility. Due to a certain degree of work hardening, the cold-rolled steel plate has low toughness, but it can achieve a better yield ratio, and is used to cold-bend parts such as spring sheets. At the same time, because the yield point is closer to the tensile strength, there is no risk of dan

  What is high strength steel plate?       High-strength steel plate refers to the grade Q420 steel, which has high strength, especially in the normalized or normalized and tempered state, and has high comprehensive mechanical properties.       Mainly used for large ships, bridges, power station equipment, medium and high pressure boilers, high pressure vessels, rolling stock, hoisting machinery, mining machinery and other large welded structures. One of the key areas is the application in the body. In order to improve the bearing quality of the car, reduce the cost of automobile manufacturing, and reduce fuel consumption, the application of high-strength steel plates in domestic and foreign automobile manufacturing is increasing, and the manufacturing process of frame parts A big change from the original mass production process. It is mainly used to manufacture structural parts such as automobile beams, beams, transmission shafts and car chassis parts.

  What is steel plate         Steel plate is a flat steel with a large aspect ratio and surface area. The steel plate is divided into two types: thin plate and thick plate according to the thickness. Thin steel sheets are steel sheets with a thickness between 0.2-4mm produced by hot rolling or cold rolling. The width of the thin steel plate is between 500-1400mm. According to different uses, the thin steel plate is rolled from billets of different materials.          Commonly used materials are ordinary carbon steel, excellent carbon steel, alloy structural steel, carbon tool steel, stainless steel, spring steel and electrical silicon steel. They are mainly used in the automotive industry, enamel industry, electrical industry, machinery industry and other sectors. In addition to direct delivery after rolling, thin steel sheets are also available in pickling, galvanized and tin-plated. Thick steel plate is a general term for steel plates with a thickness of more than 4mm. In practical w

  What are the materials of steel plates        Common steel plates are made of ordinary carbon steel, stainless steel, high-speed steel, high manganese steel, etc. Their main raw material is molten steel, which is a material made by mechanical pressing after the molten steel is poured and cooled. Most of the steel plates are flat or rectangular, which can not only be pressed mechanically, but also be cut with wide steel strips. The thickness of steel plates is large, and they can be divided into thin, thick and extra thick steel plates.         When purchasing steel, you need to check whether its outer layer has fold marks. If there are broken lines on the surface, this may be because the manufacturer has ears due to too much pressing down in order to improve efficiency, which will be formed when the next process is rolled. This type of steel is easy to break during operation, and it is not recommended to use.         When purchasing steel, it is necessary to ensure that its outer lay

  Introduction to flat steel        Flat steel products are commonly known as steel sheet/coil and steel plate. These are categorised in various types including hot rolled coil (HRC), cold rolled coil (CRC), metallic coated steel, organic coated steel, coil plate and reversing mill plate. 　　Most steel plate is produced in the thickness range between 5mm and 80mm. Plates are overlaps with hot rolled coil at the lower gauges.  steel plates are of two kinds, reversing mill plates and coil plates. Reversing mill plates are produced by rolling slab back-and-forth and are relatively higher in thickness compared to coil plates. On the other hand, coil plates are made by rolling in tandem mills in a single direction. 　　Steel sheet/coil thickness is usually lower than 5mm. Steel sheet products also include hot rolled sheet, cold rolled sheet, metallic coated sheets and organic coated sheets. Hot rolling is performed at recrystallisation temperature of steel over 1700° F. At this temperature, st

   Introduction to angle steel        The angle steel can be used to form various stressed members according to the different needs of the structure, and can also be used as a connector between members. It is widely used in various building structures and engineering structures, such as house beams, bridges, transmission towers, hoisting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, cable trench supports, power piping, bus support installation, warehouse shelves, etc. 　　The angle steel is a carbon structural steel used for construction. It is a simple section steel, mainly used for metal components and plant frames. Good weldability, plastic deformation performance and certain mechanical strength are required in use. The raw steel billet for angle steel production is low carbon square steel billet, and the finished angle steel is delivered in the hot rolling forming, normalizing or hot rolling state.

  Specification of angle steel        It is mainly divided into two categories: equal angle steel and unequal angle steel, among which unequal angle steel can be divided into unequal edge equal thickness and unequal edge unequal thickness. 　　The specification of angle steel is expressed by the dimension of side length and side thickness. At present, the specification of domestic angle steel is 2-20, and the number of centimeters of side length is taken as the number. The same angle steel often has 2-7 different edge thicknesses. The imported angle steel shall be marked with the actual size and thickness of both sides and relevant standards. Generally, large angle steel is more than 12.5cm long, medium angle steel is between 12.5cm and 5cm long, and small angle steel is less than 5cm long. 　　The order of inlet and outlet angle steel is generally based on the specifications required in use, and the steel grade is the corresponding carbon steel grade.

  Type and specification of angle steel        It is mainly divided into two types: equal leg  angle steel  and unequal leg angle steel. Unequal leg angle steel can be divided into two types: unequal leg equal thickness and unequal leg unequal thickness. 　　The specification of angle steel is indicated by the dimension of side length and side thickness. At present, the specification of domestic angle steel is 2-20, with the number of centimeters of side length as the number. The same angle steel often has 2-7 different side thicknesses. The imported angle steel shall be marked with the actual size and edge thickness of both sides and relevant standards.

  Anti-corrosion measures for I-beam and angle steel       With the wide range of application of  I-beam  and  angle steel , it involves industrial plants, door awnings, car sheds and other industries, and even steel structure adding floors, platforms, mobile houses and other projects. The use of I-beams and angle steels is too many, which also makes steel structure engineering more popular. Since there are shortcomings, there must be preventive measures. There are many anti-corrosion measures. Today we will introduce three methods. 　　Method 1: thermal spraying aluminum (zinc) composite coating 　　This is a long-term anti-corrosion method with the same effect as hot-dip galvanizing. The specific method is to sandblast and remove rust on the surface of the steel member first to expose the metal luster and roughen the surface. Then, the continuously sent aluminum (zinc) wire is melted with an acetylene - oxygen flame and blown to the surface of the steel member with compressed air to form

  Application characteristics of I-beam        The moment of inertia of the two principal axes of the section is relatively different due to the relatively high and narrow section size of the  I-beam , whether it is ordinary or light, so it can only be directly used for members bent in the plane of its web or to form a lattice load-bearing member. It is not suitable for axial compression members or members with bending perpendicular to the plane of the web, which limits its application. I-beam is widely used in buildings and other metal structures. 　　Due to the relatively high and narrow section size of common I-beam and light I-beam, the moment of inertia of the two main axes of the section is quite different, which makes its application scope very limited. The use of I-beam shall be selected according to the requirements of design drawings. 　　In structural design, I steel shall be selected according to its mechanical properties, chemical properties, weldability, structural size, etc.

 Classification of round steel 　　 Round steel  refers to solid strip steel with circular section. Its specification is expressed in diameter, in millimetres (mm). For example, "50mm" means round steel with a diameter of 50mm. 　　Round steel is divided into hot rolled, forged and cold drawn. The specification of hot rolled round steel is 5.5-250mm. Among them, 5.5-25mm small round steel is mostly supplied in bundles of straight bars, often used as reinforcement, bolts and various mechanical parts; Round steel larger than 25 mm is mainly used for manufacturing mechanical parts, seamless steel pipe blank, etc. 　　Classification by chemical composition 　　Carbon steel can be divided into low carbon steel, medium carbon steel and high carbon steel according to its chemical composition (i.e. carbon content). 　　According to the quality of steel, it can be divided into ordinary carbon steel and high-quality carbon steel. 　　According to the different manganese content, it can be divided

Introduction to 20 # carbon steel plate       20 # belongs to superior carbon steel, which complies with GB/T711 standard. 20% of 20 # steel refers to carbon content, which is 0.2%, belonging to low carbon steel. Steel can be divided into low carbon steel, medium carbon steel and high carbon steel. Mild steel - carbon content is generally less than 0.25%; Medium carbon steel - carbon content is generally between 0.25 and 0.60%; High carbon steel - carbon content is generally greater than 0.60%. 　　Domestic and international correspondence of 20 # steel plate: refer to the corresponding steel grade: China's GB/JB standard steel grade is 20, China's Taiwan CNS standard steel grade S20C, Germany's DIN standard material number 1.0402, Germany's DIN standard steel grade CK22/C22.
