Heat treating 4140
Heat treating 4140
(OP)
Is it possible to heat treat 4140 without doing an oil quench? Very small parts, ~ 5mm diameter x 10 mm long. Through hardened HRC 52-55.

But, that would be much more expensive than an oil quench. Without some type of accelerated cooling, you aren't going to make 50 HRC.
