ASTM A572 Qib 50 Hom 2 ASTM A572 / A572MSteel Phaj
High Strength Low Alloy Phaj Khoom Taw Qhia
ASTM A572 / A572M tus qauv yog thawj zaug hauv xyoo 1964, thiab tau dhau los ua ib tus qauv siv dav tshaj plaws rau kev tsim cov khoom steel. Cov hlau no tau siv dav hauv ntau daim ntawv thov thoob plaws ntiaj teb hauv ntau yam kev lag luam. Nws tau tsim los muab cov khoom siv muaj zog, tsis tshua muaj alloy siv rau hauv cov txuas hniav, cov tsev, thiab lwm yam kev siv cov qauv.

Ib qho ntawm qhov zoo ntawm ASTM A572 Qib 50 Hom 2 ASTM A572 / A572M steel yog nws lub zog. Cov hlau no muaj lub zog ua haujlwm siab thiab muaj qhov hnyav-rau-lub zog sib piv. Qhov no ua rau nws zoo tagnrho rau kev siv ntau yam kev tsim kho. Tsis tas li ntawd, ASTM A572 Qib 50 Hom 2 ASTM A572 / A572M steel yog qhov yooj yim rau kev tsim thiab vuam.
Yield zog yog qhov kev txwv ntawm ASTM A572 Qib 50 Hom 2 ASTM A572 / A572M thaum yielding tshwm sim, uas yog, kev ntxhov siab tiv thaiv micro-yas deformation. Lub zog sab nraud ntau dua li lub zog tawm los yuav ua rau ASTM A572 Qib 50 Hom 2 ASTM A572 / A572M qhov chaw ua haujlwm ruaj khov thiab tsis tuaj yeem rov qab los. Tsawg dua qhov no, ASTM A572 Qib 50 Hom 2 ASTM A572 / A572M qhov chaw yuav rov qab los rau lawv qhov qub.
Lub zog tensile yog qhov tseem ceeb ntawm kev hloov pauv ntawm cov yas deformation mus rau hauv zos concentrated yas deformation. Nws tseem yog qhov siab tshaj plaws load-nqa peev xwm ntawm ASTM A572 Qib 50 Hom 2 ASTM A572 / A572M nyob rau hauv qhov nro zoo li qub. Lub zog tensile yog qhov ua haujlwm uas ua rau lub siab tshaj plaws ntawm cov yas deformation ntawm ASTM A572 Qib 50 Hom 2 ASTM A572 / A572M. Lub deformation ntawm tensile specimens yog ib yam ua ntej lawv dais lub siab tshaj plaws tensile kev nyuaj siab, tab sis tshaj li ntawd, ASTM A572 Qib 50 Hom 2 ASTM A572 / A572M pib caj dab, piv txwv li concentrate deformation.
