Hello. I need to ensure that both ASTM SA-193 Gr B7 and SA-194 Gr 2H materials are both fully killed. I'm unable to find reference to this in ASME section II. Is there anywhere else I should be looking?
If you review the ASME SA materials specification, under Table I, there are chemical requirements for Silicon and other necessary elements. Silicon is a potent deoxidizer and results in killed steels.
