S355 steel siv rau dab tsi?
Cov qauv hlau no yog siv rau hauv kev tsim cov nkoj thiab kev tsheb ciav hlau. S355 steel kuj pom cov ntawv thov zoo rau kev tsim cov tshuab xws li cranes thiab excavators, nrog rau hauv kev tsim vaj tsev thiab kav dej, cua tshuab thiab twj.
Tus nqi ntawm S355JR ib kg yog dab tsi?
Mild Steel, Qib: S355JR – 0.61 USD/kg|610 USD / ton
Qhov txawv ntawm S275JR thiab S355JR yog dab tsi?
S275JR yog carbon hlau, thaum S355JR yog cov hlau tsis tshua muaj hlau. Ob leeg carbon steel S275JR thiab S355JR qis alloy steel yog nyob rau hauv EN10025-2 tus qauv. S355JR cov hlau tsis tshua muaj hlau yog qib steel siab dua li cov hlau S275JR.
