Hi everybody
I have one 4140 45-50rc job. It’s “L” shape with 0.75” x 2.37”x7.0”. It has one 0.5 p.f. Blind hole on 7.0” side with depth 6.7” and top of the “L” shape I have 0.2” lip with horizontal & vertical full radius and there is other three tap holes. I’m thinking to do from 4140 annealed and then after does heat treat but my question is after h.t there is any chance to change dimension? This is first time I” m dealing with 45-50rc any suggestion it’s useful
