S420NL pereti maitai
S420NL maitai he pai weldability hanganga kōeke maitai. Ko nga whakaritenga whaanui mo te whakapiri pewa o nga tira kua tohua me rite ki te EN 1011-2.
Whakatauritea te S355N, S420NL te karaehe rino he nui ake te tuku me te kaha tensile. Ko te koeke rite o S420NL he S420ML.
He nui te wheako o te maitai Gnee ki te hanga S420NL. I mahi tahi matou me te mira wuyang o HBIS ki te whakaputa i te max matotoru 300mm i roto i te hangarau remelting electroslag. Ko ta matou painga ka taea e matou te tuku taonga i roto i te waa tuku tere, ahakoa i roto i te pereti kotahi i roto i nga korero o mua.
