P355nl2 steel hlau yog lub thawv loj European steel phaj uas siv EN10028 tus qauv. Nws belongs rau lub hom ntawm Wugang Science thiab Technology Department thiab tuaj yeem welded los ntawm normaling zoo lis hlau daim hlau. Muaj plaub qib: P355N (Chav Chav Ntsuas (P355NH (kub), P355NL1 (tsawg dua (tshwj xeeb tsawg kub). P355Nl2 Cov Pob Tsuas yog siv nyob rau hauv roj av, tshuaj, boiler thiab lwm yam lag luam los tsim cov rog thiab lwm yam khoom siv thiab cov qauv txheej txheem.
