S355J2WP weathering steel coil what is the chemical composition?

In recent years, in line with the development trend of iron and S355J2WP weathering steel coil steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which S355J2WP weathering steel coil are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.

In our impression, stainless steel, as the name implies, will not rust, which is why many people choose stainless steel. Stainless steel has beautiful appearance, corrosion resistance, wear resistance, high strength, so it has a certain charm. In the past few decades, S355J2WP weathering steel coil, stainless steel has been widely used in all aspects of industry and daily life. Under normal conditions, stainless steel will not rust. Improper use, such as long-term exposure to seafood and other salt environment, stainless steel surface will also occur corrosion.

S355J2WP weathering steel coil, Wear resistant steel plate has good wear resistance:
The chemical composition of the alloy wear-resistant layer is 4-5% carbon and 25-30% chromium. The volume fraction of Cr7C3 carbide in the metallographic structure is more than 50%. The macro hardness is HRC56-62 and the hardness of chromium carbide is HV1400-1800. Because the carbides are distributed perpendicularly in the direction of wear, even when compared with cast alloys of the same composition and hardness, the wear resistance is more than doubled.

S355J2WP weathering steel coil controlled rolling is that, on the basis of adjusting the chemical composition of S355J2WP weathering steel coil, by controlling the heating temperature, rolling temperature, deformation system and other process parameters, the change law of austenite structure and the microstructure of phase transformation products are controlled, so as to achieve the purpose of refining the structure and improving the strength and toughness of S355J2WP weathering steel coil.

"We can supply carbon steel plate, S355J2WP weathering steel coil, hot rolled plate and structural steel sheet with high quality and various size.
