ASTM A572 GR50/60 Kauv Welded Yeeb Nkabyog aSiab-Lub zog qis-Alloy (HSLA) steel, uas yog microalloyed nrog cov ntsiab lus xws liniobium, vanadium, lossis titanium. Qhov sib ntxiv ntawm cov hlau alloying no txhim kho covlub zog thiab durabilityntawm cov hlau tsis muaj qhov nce nws qhov hnyav. Raws li qhov tshwm sim, cov khoom siv no feem ntau siv rau hauv daim ntawv thov qhov twgyuav tsum muaj lub zog siab thaum qhov hnyav tseem yog qhov tseem ceeb.
