Gentelman,
Continuing our theme. I was searching for 12L14 alloy equivalent in 10 years old catalog. No hits. Today I've found a new book with materials' cards and voila:
12L14 =~ 11SMnPb30 known for its lack of thermal hardening.Few pages further and we have 36SnMnPb28. This is some change in carbon (0,36%) but now it can be austenitized! The problem is that the hardness written was ~100 HB =~ 10 HRC - the same as our 2H13 (0,2C
13% Cr, ~X20Cr12) stainless steel. This is quite small value so that I think this steel can't be hardened using Martensite structure. Correct me if I am wrong.My question is do you know or use such steel with lead (superb for turning) which can be hardened?
Cheers, ______________________________________________________________________
