ASTM A572 steel hlau

Hlau Phaj ASTM A572 / A572M
ASTM A572 Specification yog hais txog High-Strength Low-Alloy Steel Phaj rau cov qauv tsim, ntawm 5 qib steel ntawm 42, 50, 55, 60 thiab 65, Qib 50 yog ib qho hlau feem ntau hauv cov ntawv thov uas xav tau ntau lub zog thiab qhov hnyav dua, siv steel phaj ntawm qib no uas tsis yog cov pa roj carbon zoo tib yam yuav ua rau cov qauv steel nrog tib lub zog steel tab sis sib dua.
