steel S355J2W mechanical properties ASTM equivalent

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 steel S355J2W mechanical properties steel products are supplied in time, with reliable quality and perfect and thoughtful after-sales service. Meanwhile, we have huge steel S355J2W mechanical properties 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.

The company has strict control on the quality of steel S355J2W mechanical properties. Each steel S355J2W mechanical properties is inspected for the whole process, including raw material purchase, production process according to the procedures and relevant regulations. According to the technical standards and technical requirements, the composite quality inspection is carried out to confirm whether the steel S355J2W mechanical properties meets the specified quality requirements. If the steel S355J2W mechanical properties does not meet the quality requirements, the non conformity control shall be implemented, and the unqualified steel S355J2W mechanical properties shall be removed, marked, registered and effectively isolated; the steel S355J2W mechanical properties shall be inspected and confirmed for acceptance, release and delivery, and the quality certificate shall be issued.

Flat steel is a kind of steel with rectangular cross-section and blunt edges at the edges and corners. It is usually 12-300 mm wide and 3-60 mm thick. Compared with steel S355J2W mechanical properties ordinary steel plate, the utilization rate of flat steel is increased by one to five percentage points. Moreover, flat steel can be produced with fixed thickness, width and length according to the user's requirements, which saves the cutting process for users, reduces the consumption of labor and materials, and also reduces the processing loss of raw materials, saving time, labor and material.

At the initial stage of corrosion, the rust layer on the surface of weathering steel is denser than that of carbon steel, steel S355J2W mechanical properties, and there are relatively few cracks and holes. After 25 days, delamination occurs in some parts of carbon steel and weathering steel, and there is no difference in corrosion products, mainly due to the role of alloy elements in the rust layer. The precipitation of Cu and Cr alloy elements in the weathering rust layer can resist the invasion of moisture and harmful ions in the atmosphere, and further corrosion of steel and base metal can be prevented, so as to achieve the effect of atmospheric corrosion resistance.

The carbon content of steel S355J2W mechanical properties, medium carbon steel plate is 0.25% - 0.60%. In addition to carbon, it can also contain a small amount of manganese (0.70% - 1.20%). The medium carbon steel plate after quenching and tempering has good comprehensive mechanical properties. The highest hardness is about HRC55 (hb538) and σ B is 600-1100mpa.
