ASTM A572 Qib 50 Carbon Steel H BARS yog ua los ntawm ntau lub zog ntawm 450-600MPA, thiab ib qho elongation ntawm ntau dua los yog sib luag rau 18%.
Lawv haum rau hnyav {{0} duty worksure qauv xws li high {1} REEve Tsev Tub Ntxhais Core thiab Loj Hoobkas Tsev Hlau Beams. Nws cov ntsiab lus carbon yog tsawg dua los yog sib npaug rau 0.23%, thiab niobium (nb) 0.005-0.05% thiab vanadium (ceiiw tsawg dua lossis sib npaug ntawm 0.45%).
A572 Qib 50 Hlau Kub -}} rolled, thiab cov tuab piv ntawm lub vev xaib yog qhov zoo. Piv txwv li, lub sijhawm ntawm inertia ntawm W16 × 36Y, uas yog ntau tshaj 20% yog ntau dua li cov roj carbon hlau, thiab haum rau loj- spi spur lub teeb yuag. Cov nplej yog ua kom zoo rau
ASTM Qib 8 Los Ntawm Kev Tswj Cov Txheej Txheem Rollling, thiab Qhov Cuam Tshuam Ntawm- 20℃yog loj dua los yog sib npaug ntawm cov phiaj xwm txias-cheeb tsam.
ASTM A572 Qib 50 H Nqis ua raws li American Standard A572 / A572M-18, thiab nws cov kev ua tau zoo yog piv rau lub teb chaws qauv Q355d. Nws yog dav siv nyob rau hauv export steel qauv, tsuas Machinery ntas thiab choj lub ntsiab lub ntsiab. Nws cov ntsiab lus phosphorus thiab cov leej faj cov ntsiab lus yog tsawg dua lossis sib npaug ntawm 0.04% thiab 0.05% feem, txhawb nqa arc vuam, thiab txhim kho kev ua haujlwm ntawm 30%.
