1. Brief introduction of S355J0W steel plate:
S355J0W is European standard atmospheric corrosion-resistant steel, which belongs to weather-resistant steel plate. It is a low-alloy steel made by adding a certain amount of alloy elements to ordinary steel. The atmospheric corrosion resistance of weathering steel is 2-8 times that of ordinary carbon steel, and it has good mechanical properties, welding properties, etc., and the longer the time, the more obvious the corrosion resistance effect.
2. S355J0W improved atmospheric corrosion resistant steel
A certain amount of alloying elements are added to the steel, such as P, Cu, Cr, Ni, Mo, in order to increase the resistance to air corrosion, and under the influence of climatic conditions, an automatic protective oxide will be regenerated on the base metal.
3. Delivery status of S355J0W:
Delivered in hot rolled, normalized or normalized rolled condition.
Four, S355J0W steel plate executive standard:
S355J0W implements EN10025-5:2004 standard.
5. S355J0W improved atmospheric corrosion resistant steel
A certain amount of alloying elements are added to the steel, such as P, Cu, Cr, Ni, Mo, in order to increase the resistance to air corrosion, and under the influence of climatic conditions, an automatic protective oxide will be regenerated on the base metal.
