S355J0W steel plate features

S355J0W steel plate Features:

Weather resistance: S355J0W steel plate adds special alloying elements in the manufacturing process, such as copper, phosphorus, chromium, nickel, etc. These elements can form a dense oxide protective film on the surface of the steel plate, effectively resisting atmospheric corrosion and extending the service life. Its atmospheric corrosion resistance can be 2-8 times that of ordinary carbon steel, and the longer the time, the more obvious the corrosion resistance effect.

Mechanical properties: S355J0W steel plate has good mechanical properties, including high yield strength, tensile strength and elongation. Its tensile strength range is 410-630MPa, the yield point is ≥335MPa, the elongation after breaking should be greater than or equal to 20%, to meet the needs of various structural parts.

Welding performance: S355J0W steel plate has excellent welding performance and is suitable for various welding processes, which is easy to connect and process in the manufacturing process.

Processing performance: The steel plate can be cut, bent, stamping and other processing, easy to make into various shapes and sizes of structural parts, to meet different design needs.

The chemical composition of S355J0W steel plate mainly includes carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S) and trace alloying elements such as chromium (Cr), nickel (Ni), copper (Cu) and molybdenum (Mo). Among them, the carbon content should be less than or equal to 0.16%, the silicon content should be less than or equal to 0.5%, the manganese content should be 0.5-1.5%, and the phosphorus and sulfur content should be less than or equal to 0.010%. The proportion and content of these elements have an important effect on the performance and weather resistance of the steel plate.

The delivery status of S355J0W steel plate includes hot rolling, normalizing or normalizing rolling status. These different delivery states have different effects on the structure, performance and subsequent processing of the steel plate. Customers can choose the appropriate delivery status according to their specific needs and order requirements.
