Carbon steel top 6 factories in China

The company adheres to the service concept of "you give the order to me and I leave the satisfaction to you". Over the years, our 08CUPVRE plate steel products are supplied in time, with reliable quality and perfect and thoughtful after-sales service. Meanwhile, we have huge 08CUPVRE plate steel stocks all the year round. The company long-term pursues the principle of quality first, customer first, quality for survival, reputation for development, and perfect service to win the users.

Hot rolled steel for cold forming can be divided into general purpose, stamping, deep drawing and ultra deep drawing according to its use. Common grades include 08CUPVRE plate, DD11, DD12, SPHC, SPHD, SPHE steel. Hot-rolled steel for cold forming produced by our company uses low-carbon component, and has good stamping performance, welding performance and high dimensional accuracy. This material is widely used in various cold forming industries.

Steel plates for high-rise buildings have the properties of easy welding, earthquake resistance, and low-temperature impact resistance, and are mainly used in large-scale projects such as high-rise buildings, super-tall buildings, large-span stadiums, airports, exhibition centers, and steel structure workshops. Compared with ordinary Q235B / Q345B steel plates, these plates 08CUPVRE plate for high-rise buildings have upper limits on yield strength and improved tensile strength, and have requirements for carbon equivalent and yield ratio indexes.

The purpose of 08CUPVRE plate quenching is to transform the supercooled austenite into martensite or bainite to obtain a martensite or bainite structure, and then cooperate with tempering at different temperatures to greatly improve the strength, hardness, performance, fatigue strength, toughness, and wear resistance etc. of 08CUPVRE plate. So as to meet the different use requirements of various mechanical parts and tools. Quenching can also help to get the ferromagnetic, corrosion resistance and other special physical and chemical properties of certain special steels.

20Mn2 steel has medium strength, and the properties of 20Mn2 steel and 20Cr steel are similar. The impact toughness and weldability of 20Mn2 steel at low temperature are better than those of 20Cr steel. The plasticity and machinability of 20Mn2 steel are high during cold deformation. The hardenability of 20Mn2 steel is higher than that of corresponding carbon steel, 08CUPVRE plate. Chemical composition of 20Mn2 steel: C: 0.17-0.24, Si: 0.17-0.37, Mn: 1.40-1.80. Mechanical properties of 20Mn2 steel: tensile strength ≥ 785 MPa, yield strength ≥ 590 MPa, elongation after fracture ≥ 10%, section expansion rate ≥ 40%, impact absorbed energy ≥ 47J.

Our company will accept the product quality objection registration record, pass it to the 08CUPVRE plate production unit and relevant departments, and timely coordinate the supervision of product 08CUPVRE plate quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
