Hello to all.
I'm trying to figure out wich is the best material for making cold formed
bolts wich need to have 25 HRc of maximum hardness.
I was thinking about using 1022 steel wich is suitable for cold forging but
I'm afraid the hardness process will be much more complicated than just
quenching and tempering.
1022 steel will not harden using the ordinary methods, but it is nice to
cold head.
Then I was thinking about 1045 steel but I'm not sure how good it would be
for the cold forging process.
1045 is much more useful for threaded screw use, cold heads well and
hardens well.
Do you have any hints or advices about this?
How do you plan to thread them? Cut thread is more difficult chucking.
Thread rolling is the standard procedure.
Thank you as always!
Leonardo.
