hardening 4130 - Metal and Metallurgy engineering - Eng-Tips

Aug 16, 2011 · 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.
