(OP)
I beleive the 13 Cr is the same as Grade 420 modified, but what about Super 13 Cr? Does it have the same chemical composition as 13 Cr? What is the values for yield, tensile on this material?

(OP)
I beleive the SM13CRS grade has 95 ksi yield?! Are you sure this is the Super 13 Cr? The 420 modified (13 Cr) has a yield stress of 110 ksi (NACE approved).
