Hello Ed, I plan to thread the bolts with rollers. The main concern for me was if the 1045 steel can be cold forged for this purpose of making the head of the bolts.
I've machined forged camshafts of 1045 steel but they were made with the hot forging method. I must say I have zero experience in the process of forging, we only machined and heat treated the camshafts but the forging process was made by another company. 2018-07-10 13:25 GMT-03:00 Leonardo Marsaglia <ldmarsag...@gmail.com>: > Hello Dave. > > The idea is to achieve a maximum hardness 25 HRc after cold forging with > heat treatment.
