Cov ntsiab lus carbon tsawg dua lossis sib npaug li 0.23%, nrog ntxiv niobium (0.005–0.05%) thiab vanadium (0.01–0.15%) txhawm rau txhim kho vuam kev ua tau zoo los ntawm kev nplua nplej ntxiv (CEIIW Tsawg dua lossis sib npaug rau 0.45%). Kub- dov beams optimize lub flange - mus rau -web thickness piv rau siab zog thiab lub teeb tsim.
Cov txheej txheem dov tswj tau ua kom zoo dua cov nplej rau ASTM qib 8, thiab qhov cuam tshuam lub zog ntawm -20℃yog siab dua lossis sib npaug rau 27J, ua kom haum rau cov dej txias -cov haujlwm hauv cheeb tsam. ASTM A572 Qib 50 H-beams ua raws li A572 / A572M-18 thiab sib piv rau lub teb chaws tus qauv Q355D.
Mechanical Properties ntawm ASTM A572 Qib 50 H-Beam
| Specification | Yield zog (MPa) | Tensile zog (MPa) | Elongation (%) | Moment of Inertia (Iₓ, in⁴) |
|---|---|---|---|---|
| W16×36 | 345 | 450–600 | Ntau dua lossis sib npaug li 18 | 448 |
Lus Cim: Qhov zoo tshaj plaws flange - rau -web piv ua rau ntu ntau dua 20% sib dua li cov pa roj carbon zoo tib yam, zoo tagnrho rau cov qauv loj - ncua lub teeb yuag.
Daim ntawv thov ntawm ASTM A572 Qib 50 H-Beam
ASTM A572 Qib 50 H-beams yog dav siv nyob rau hauv siab - nce lub tsev tub ntxhais raj, muab kev txhawb zog thiab ruaj khov.
Lawv kuj tau siv rau hauv lub Hoobkas loj lub tsev kab teeb thiab kev lag luam steel qauv, muab lub zog siab thiab weldability zoo heev rau kev thauj khoom -cov ntaub ntawv kabmob.
Export steel qauv, mining machinery thav duab, thiab choj lub ntsiab beams tau txais txiaj ntsig los ntawm A572 Qib 50 H-beams. Lawv cov phosphorus thiab sulfur cov ntsiab lus (tsawg dua los yog sib npaug li 0.04% thiab 0.05%) txhawb cov nplaim txiav thiab submerged arc vuam, txhim kho kev ua haujlwm ntawm 30%.
