Can 516 gr 70 be steel killed?

Yes, ASTM A516 Grade 70 steel can be killed. "Killed" steel refers to steel that has been treated to remove oxygen and other gases, which improves its mechanical properties and reduces the likelihood of defects. This is typically achieved through the addition of deoxidizing agents during the steelmaking process. Therefore, A516 Gr 70, which is often used in pressure vessel applications, can be produced as killed steel for enhanced performance.
