52100 ductility
(OP)
What is the ductility of 52100 tempered (after quenching) at various temperatures? I am looking for a published chart if possible. Also, would marquenching vs oil quenching have an impact on ductility?

RE: 52100 ductility
marquenching and regular quenching are different heat treat processes designed to do different things to the structure.
I Think MIL-HDBK-5J covers heat treat and physical properties of steels. Search this fourm for a link to where to get it (70MB download).

Are you sure this mil-spec will have the elongation of 52100 tempered at 300F,400F,500F,600F,700F,800F,900F,1000F?
52100 is not usually considered for use in aerospace applications except as bearings with hardness over 60 HRC.
Heat Treater's Guide and Vol 4 contain ductility/elongation data on steels like 4140 and 4340, but not 52100. Since the m/s is carbide in tempered martensite, how is ductility affected? Is there a sudden increase when tempered at 700-750F?

I love materials science!
RE: 52100 ductility
Here is a reference to a paper on 52100. The only problem is that is isn’t available from Storming Media. You might contact the Naval Post Graduate School Library or the Linda Hall library.

Allows only heat treatment to 63RC minimum.
