What does steel grade Corten B steel plate for construction machinery mean

At the same time of doing well in Corten B steel plate for construction machinery 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 Corten B steel plate for construction machinery 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.

Carbon structural steel refers to the kind of steel which is mainly used in construction and engineering structures without adding alloy elements. Among all kinds of steel, Corten B steel plate for construction machinery, carbon structural steel has a large output, the most extensive use and low price. Carbon structural steel is often rolled into various steel bars (round steel, square steel, flat steel, hexagonal angle steel, etc.), section steel (I-beam, angle steel, channel steel, L-shaped steel, etc.), profiled steel and steel plate. Carbon structural steel is mainly used in buildings and engineering structures such as workshops, bridges, ships, etc. Generally, heat treatment is not required for carbon structural steel.

The Corten B steel plate for construction machinery processing performance is good. Due to the uniform control of steel plate performance, excellent performance coordination and good toughness guarantee, the steel plate bending processing, drilling, cutting and other mechanical processing properties are excellent. In addition, the surface of the Corten B steel plate for construction machinery steel plate is smooth and beautiful by inhibiting and removing oxide scale from slab heating to rolling process and heat treatment in furnace without oxidation atmosphere.

The principle of stainless steel, the corrosion resistance of Corten B steel plate for construction machinery, stainless steel depends on chromium, it depends on a very thin, solid and fine stable chromium rich oxide film (protective film) formed on its surface, to prevent oxygen atoms from continuing to infiltrate and oxidize, so as to obtain the corrosion resistance.

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, Corten B steel plate for construction machinery. 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.
