A573 grade 70 carbon steel plate sheet are on hot selling in Bangladesh

At the same time of doing well in A573 grade 70 carbon steel plate sheet production and operation, Yunnan company focused on completing the four phases of technical transformation construction projects, realizing industrial upgrading, improving equipment level, and laying a good foundation for the future development of the company. In the A573 grade 70 carbon steel plate sheet technological transformation project, pollution control facilities have been built synchronously, and a large number of comprehensive utilization projects, such as comprehensive sewage treatment and recycling project, blast furnace gas waste heat and residual pressure power generation, have been invested and constructed.

The mechanical properties of A573 grade 70 carbon steel plate sheet steel plate are related to elastic or inelastic reaction or related to stress-strain relationship. Tensile strength, yield point, elongation and impact absorption energy are the main indexes to express the mechanical properties of hot rolled steel plate. Its value represents the ability of steel A573 grade 70 carbon steel plate sheet to resist various actions, which is the main criterion to evaluate the quality of steel material, and also the main basis for material selection and strength calculation in steel plate design.

Bridge steel plate is specially used for erecting railway or highway bridges. A573 grade 70 carbon steel plate sheet, bridge steel plate is required to have high strength and toughness to bear the load and impact of rolling stock, and have good fatigue resistance, certain low temperature toughness and atmospheric corrosion resistance. The bridge steel plate used for bolt welding bridge should also have good welding performance and low notch sensitivity.

As the thickness and hardness of A573 grade 70 carbon steel plate sheet increase, the tendency to crack at the cutting edge increases. In order to prevent the A573 grade 70 carbon steel plate sheet from cutting cracks, preheating should be carried out before A573 grade 70 carbon steel plate sheet cutting. Special attention should be paid to preheating to make the entire A573 grade 70 carbon steel plate sheet interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole A573 grade 70 carbon steel plate sheet cannot be preheated, the partial preheating method can be used instead.

According to GB 11251 technical standard, the chemical composition of 40Cr structural steel plate is as follow: Carbon content is 0.37-0.44 %, Silicon content is 0.17-0.37%, Manganese content is 0.50-0.80%, Chrome content is 0.80-1.10%. 40Cr steel is usually in shape of 40Cr steel plates and bars. A573 grade 70 carbon steel plate sheet, GB 11251 is for 40Cr structural steel plate with thickness range of 4-30mm. The tensile strength of 40Cr structural steel plate is 550-800Mpa. And its min. Elongation is 16%.
