FAQ

Q: S355JR steel kaum hlau qib yog dab tsi?

A: Steel qib S355JR yog siv los tsim cov khoom kub-kuav los tiag thiab cov khoom siv ntev, uas yog siv tom qab tsim cov tsev steel.

Q: Qhov txawv ntawm S275JR lub kaum sab xis steel thiab S355JR lub kaum sab xis yog dab tsi?

A: 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.

Q: Puas yog S355 lub kaum sab xis hlau zoo dua li S275 steel hlau kaum?

A: Cov qib ntawm cov hlau no muaj zog dua li nws cov S275 counterpart nrog qhov tsawg kawg nkaus yield zog ntawm 355 N / mm2 ua rau nws lub npe S355. Qib no kuj muaj nyob rau hauv phaj, puag ncig bar, tiaj tus bar, thiab txawm muaj nyob rau hauv blocks.
