1: DIN S355J0 steel introduction
S355J0 steel plate is a European standard low alloy high strength steel plate, belonging to the European standard brand. "S" indicates that the steel sheet is ferrous metal smelting, "355" is the yield strength of the steel sheet, "J" is the heat treatment process of the steel sheet, and "0" is the impact temperature of the steel sheet.
