S355J2W steel plate is a weather resistant steel plate, by adding special alloying elements, such as chromium, nickel and molybdenum, so that it has excellent weather resistance. This steel plate is mainly used in the manufacture of structures and components that need to be used in harsh weather conditions.
S355J2W steel plate features:
High strength: S355J2W steel plate has high tensile strength and can withstand heavy loads and extreme environmental conditions.
Strong weather resistance: After special treatment, the steel plate can maintain stable performance under harsh climatic conditions and is not susceptible to corrosion and oxidation.
Wear resistance: S355J2W steel plate has good wear resistance and is suitable for working environments that require frequent contact and friction.
Easy to process: the steel plate is easy to process and weld, and can be cut, bent and punched according to actual needs.
The chemical composition of S355J2W steel plate mainly includes carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S) and a small amount of chromium (Cr), nickel (Ni), molybdenum (Mo) and other elements. The content of these elements is precisely controlled to ensure that the steel plate has excellent mechanical properties and weather resistance.
The mechanical properties of S355J2W steel plate mainly include tensile strength, yield strength, elongation and other indicators. Among them, the tensile strength is between 450-680MPa, the yield strength is between 275-400MPa, and the elongation is between 18-28%. These indexes reflect the bearing capacity and deformation characteristics of the steel plate, which is an important basis for structural design.
S355J2W steel plate has excellent mechanical properties and corrosion resistance, so it is widely used in Bridges, buildings, ships, vehicles and other fields. In terms of Bridges, S355J2W steel plates can be used to manufacture load-bearing structures and support systems of Bridges to improve the bearing capacity and stability of Bridges. In terms of construction, it can be used to manufacture structural frames and walls of high-rise buildings, and improve the earthquake resistance and wind resistance of buildings. In the manufacture of ships and vehicles, S355J2W steel plates also play an important role, such as the structure and deck for the manufacture of hulls, as well as the chassis and frame of vehicles.
