P275 thiabA516 GR 70 Yog ob qho tib si steels siv nyob rau hauv siab lub nkoj tsim, nrog P275 ua tus qauv European cov hlau thiab A516 GR 70 yog tus neeg Asmeskas cov qauv hlau.
P275 yog European Cov Txheej Txheem Hlau Carbon Hlau rau cov nkoj siab, conforming rau cov qib xws li P275NH thiab P275NL1 raws cov lus qhia. P275NH txhais tau hais tias ib txwm muaj, weldable nplua zoo {{}}} nplej hlau. P275NL1 txhais tau ib txwm muaj, weldable nplua zoo {{mak}} nplej steel rau tsawg- qhov kev thov kub.
A516 Gr 70 yog cov pa roj carbon hlau rau nruab nrab thiab qis - kub siab cov nkoj, conforming rau Asmeskas Astm thiab Asme Cov Qauv.
Tshuaj Muaj Tshuaj
P275:Noj P275NL1 ua piv txwv, ntau tshaj cov ntsiab lus (c)) yog 0.60)
A516 GR 70:Cov ntsiab lus tseem ceeb yog carbon (c), manganese (mn), thiab silicon (si). Cov pa roj carbon (c) cov ntsiab lus tsawg dua lossis sib npaug rau 0.30%. Silicon (Si) cov ntsiab lus ranges los ntawm 0.13% rau 0.45%, mangasce (m) cov ntsiab lus tsawg dua lossis sib npaug 0.035%, thiab sulfur cov ntsiab lus tsawg dua los yog sib npaug rau 0.035%.
Cov Khoom Siv Neeg Kho Tshuab
P275:Xij lub zog muaj kwv yees li 275 MPa, tensile muaj zog 370-510 mpa.
A516 GR 70:Tos lub zog ntau dua los yog sib npaug rau 230 MPa, tensile lub zog 485-620 mpa.
Kev Kho Cua Sov
P275:Feem ntau yuav tsum tau kho qhov kev kho mob kom ua tiav qhov nplua {{0} nplej Microstructure, txhim kho cov hlau lub zog thiab tawv.
A516 GR 70: Plates ≤40mm thick are usually supplied in the as-rolled condition but may be ordered normalized, stress-relieved, or normalized and stress-relieved. Plates >40mm tuab yuav tsum yog li qub.
Daim Ntawv Thov
