S280GD Steel yog dab tsi?
S280GD yog cov hlau tsis yog- alloy structural steel, ua los ntawm 98-99% hlau thiab 0.1-0.2% carbon, ntsib EN 10346 nrog qhov tsawg kawg nkaus yield zog ntawm 280 MPa. Nws yog ib lub tiaj- dov steel, feem ntau kub-dip galvanized rau corrosion kuj. Hauv S280GD, "S" qhia txog cov qauv hlau, "280" lub zog tawm los, thiab "GD" galvanization. Nws los nrog kev ua tiav zoo li + Z (zinc) thiab + ZF (zinc-hlau), haum rau kev tsim kho, tsheb, thiab lub teeb engineering. Zoo ib yam li FeE280G, nws muaj EU steel tooj ntawm 1.0244.
Lub npe S280GD yog muab los ntawm European tus qauv EN 10346 thiab sawv cev rau:
- S: Cov khoom siv qib steel.
- 280: Yam tsawg kawg nkaus tawm lub zog ntawm 280 MPa.
- GD: Haum rau kev kub kub-dip galvanization.
