Help Indentify Tool Steel /Stainless Steel
(OP)
I was wondering if anyone can help me indentify this material. It is used in High temperature automotive applications as a bushing.
C = 1.139
Mn = .540
P = .041
S = .021
Si = 2.149
Cr = 32.812
Ni = .377
Mo = 2.054
Cu = .228
Mg = .032
W = .039
V = .277
Co = .053
Sn = .012
Al = .034
Nb = .049
Pb = .007
B =.004
Se = .002
Ta = .002
Zr = .010
Fe = Remainder
Thanks

It does have black coating, we figured it was nitrided.
Given so much Carbon, that hardness was only 38 HRC, which I thought was odd.
The PM comment is very interesting, as another part we have I swore is PM but it is made up of CK20 which is an investment cast 310 stainless. I am unsure if the PM composition would be the same as the cast, or would it resemble the wrought alloy more.

If that is a steel, it would have to be made to order by a specialist alloy supplier, it doesn't seem to fit any of the international specs.
