ASTM A516 Qib 70 yog qhov ruaj khov, weldable carbon steel phaj rau cov hlab ntsha siab thiab cov boilers, paub txog nws lub zog siab thiab zoo heev toughness ntawm qis mus rau nruab nrab kub, ua rau nws zoo tagnrho rau kev thov hauv cov roj, roj, thiab fais fab kev lag luam. Nws muaj superior tensile/yield zog thiab ductility piv rau cov qib qis (xws li A516 Gr 60/65) thiab yog tus qauv rau cov khoom tseem ceeb uas xav tau kev ntseeg siab nyob rau hauv ntau yam thermal tej yam kev mob.
