ASTM A572 Lub kaum sabPuas yog lwm qhov siab - lub zog, qis {{{{}} aluminium- vanadium steel sib tshooj. Owing rau me me ntawm Columbium alloy ntsiab, kub dov A572 lub qhov khoom siv tau zoo dua li cov roj carbon steel a36.
Ua ntej, A572 muaj lub zog siab dua A36 zoo li nyob rau lub zog thiab lub zog tensile. Thib ob, nws yog ib qho yooj yim rau weld, daim ntawv thiab tshuab.

A572 Lub kaum ntse ntse Steel nta & cov txiaj ntsig
Lub zog muaj zog - rau - qhov hnyav} qhov hnyav nyhav
A572 {-} cov hlau muaj lub zog zoo tshaj plaws {2} Txoj kev siv rau cov txheej txheem uas muaj qhov hnyav yog qhov hnyav tseem ceeb.
Piv txwv li, hauv cov choj, yees, lossis loj - teev txaus steel tsim cov phiaj xwm thaum muaj peev xwm txo qhov hnyav tag nrho. Qhov no tsis yog cov nqi qis qis tab sis tseem ua kom yooj yim dua kev thauj mus los thiab kev teeb tsa.
Muaj zog dua cov pa roj carbon a36
Piv nrog feem ntau siv A36 carbon stick lub kaum sab xis, A572-50 muab cov tshuab ua haujlwm siab dua:
A36 Hlau: Raug Tawm Tawm Zog ≈ 36 Ksi (txog 250 MPA)
A572-50 Hlau: Yam tsawg kawg cov paib lub zog ntau dua los yog sib npaug rau 50 ksi (kwv yees li 345 mpa)
Qhov no txhais tau tias nrog tib tus ntoo khaub lig {{0} ntu qhov loj me, A572 {{{} {{} tuaj yeem siv cov qauv kev nyab xeeb thiab muaj txiaj ntsig zoo nqi.
Txhim khu cov khoom siv tau txhim khu kev qha
Yield zog (ys):Ntau dua los yog sib npaug rau 50 ksi (≈ 345 mpa)
Tensile lub zog (UTS):Ntau dua los yog sib npaug rau 65 ksi (≈ 450 mpa)
Elongation:Kev du yas ua tau zoo, ua kom muaj zog thiab kev tawm tsam rau qhov tsis muaj kev ntxhov siab
Cov khoom tau lees tias muaj kev sib npaug ntawm lub zog thiab kev kub siab, ua rau cov steel haum rau kev thov engineering engineering.
Qhov zoo tagnrho cov ntawv thov tshuab
Ua tsaug rau nws lub zog, kev nruj me ntsis, thiab durability, A572-50 tau siv dav hauv:
- Hlau Hlau Ua Lag Luam
- Choj Cov Txheej Txheem
- Yees thiab Trusses
- Muaj cov khoom siv
- Ntev -} span cov qauv lossis cov phiaj xwm yuav tsum tau txo qhov hnyav
Piv nrog cov pa roj carbon me me, A572 -}}}}}}}}}} 50}} 50} -} hom ruaj khov. Nws yog qhov kev xaiv zoo tshaj plaws rau cov haujlwm engineering uas ob lub zog thiab cov nqi ua tau yog qhov kev txiav txim siab tseem ceeb.
