A709 Gr 50W carbon steel plate sheet technical parameters

The company is a large A709 Gr 50W carbon steel plate sheet steel supplier and exporter specializing in steel coil, steel plate, steel tube and section steel. The company has always put service and quality first, offered reasonable price, taken small profits and quick turnover as the principle, honest and trustworthy as the purpose. The success of the company is not only the hard work and wisdom of all the employees of the company, but also the deep love of our customers. We will continue to achieve new leaps and create greater brilliance of the A709 Gr 50W carbon steel plate sheet enterprise, and make our own contribution to the development of the world economy.

P265GH grade to EN10028-2 is a non-alloy quality steel with high temperature performance. The number: 1.0425. It has good plasticity, toughness, cold bending performance and welding performance. P265GH is an executive standard of the European standard boiler vessel plate is EN10028, European pressure vessel steel plate standard 265GH, and the corresponding domestic brand is 25MnG. 25MnG is a seamless steel pipe for GB 5310-2008 high pressure boiler.

Weathering steel has good resistance to atmospheric corrosion. Although the initial investment cost of weathering steel is slightly higher than that of ordinary carbon steel. Compared with methods such as spraying anticorrosive coating on the surface of ordinary carbon steel, the later maintenance costs of ordinary carbon steel are weathering steel. 1.5-2 times. Therefore, A709 Gr 50W carbon steel plate sheet weathering steel can reduce environmental pollution and is a key promotion technology for energy saving and emission reduction. Most domestic weathering steels are painted and used, and their original intentions of no-painting and "rust prevention" have not been exerted to a greater extent.

Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the A709 Gr 50W carbon steel plate sheet quenched steel to a certain temperature and then cool it in a certain way. Tempering can reduce or eliminate the internal stress produced by quenching, reduce the hardness and strength, and improve the ductility or toughness of steel. After A709 Gr 50W carbon steel plate sheet quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.

P235GH steel material number under EN10028-2:2003 standard is 1.0345. This steel is a European pressure vessel steel. P235GH Mechanical properties: Tensile strength σb (350 ~ 480 MPa); Yield strength σs(215 MPa min.); Elongation ≥25%; Brinell hardness ≤105 ~ 140. A709 Gr 50W carbon steel plate sheet, P235GH steel chemical composition (mass fraction,%): ≤0.16 C; ≤0.35 Si; 0.60 ~ 1.20 Mn; ≤0.025 P; ≤0.010 S; ≤0.30 Cr; ≤0.30 Ni; ≤0.30 Cu; ≤0.08 Mo; ≤0.02 V; ≤0.02 Nb; ≤0.012 N; ≤0.020 Al; ≤0.03 Ti.
