EN 10155 S355K2G1W Weathering steel round bar, S355K2G1W steel bar Composition
EN 10155 S355K2G1W Weathering steel round bar is of EN 10155 standard,S355K2G1W material number is 1.8966, also named the weather corrosion resisitant steel under EN10155 Standard.The equality material in ASTM standard is A 709 Grade 50W, the equality in NFA 35502 standard is E 36 WB 4,S355 K2G1W steel plates also have equality in WBL 087,BS4360,CSA G 4021 standard.
The main alloying chemical composition of S355K2G1W steel bar is Chromium, nickle and copper ect.. The S355K2G1W steel builds a dark brown protective coated which prevents the steel from further oxidation. So S355K2G1W offer cost effective protection against atmospherice conditions without the need for painting or external treatment.
