Do any of you know of a source for 2"OD prehardened steel in the HRC 38-42 range, with material certs? I figure 4340 would be ideal, but I just haven't been able to find any. McMaster has 4140 prehard, but it's HRC 35. Everywhere else has been Rockwell 32, at best. I've done a number of searches buy 4130 steel hardness hrc
First, lets establish what hydrogen embrittlement is and how to handle it. Hydrogen embrittlement only occurs with hardened steel in the hardness range of 44Rc and up. Ya, I know, +-a few points. It can happen when hardened steel is exposed to hydrogen, often from plating baths. The part needs to be under stress.

4130 will harden to HRC 51 by water quenching. After tempering at 500 the hardness will be less. You can carburize 4130 for higher surface hardness up to 65 HRC if you have enough pieces to justify the cost of a furnace run. If you have only one piece, you can use Kasenite to surface harden with an oxy-acetelyne torch.
