SA516GR70 - Fully Killed ?
SA516GR70 - Fully Killed ?
(OP)
Hello everybody,
I've read in one Thread a post from:
INPIDI (Materials) 6 Sep 07 19:27
IF U CHECK ASTM 516 GRADE 70 SPEC U WILL NOTICE THAT BY DEFINITION IT IS KILLED STILL(THE NON KILLED/RIMMED EQUIVALENT IS 515 GR 70
In ASTM 516 spec I'm unable to find this, it seems that we can ask the supplementary requirements
S1.VacuumTreatment
S17.VacuumCarbon-DeoxidizedSteel
but if not asked, nothing says in this spec. that SA516 is fully killed ?

A-515 is also made "killed" (fully deoxidized) but to a coarse grain melting practice.
A-516 is killed and made to fine grain melting practice.
