I am asked to quote some parts made from 4140 steel. With gas nitride heat treat to 50 to 54 RC.
These are small parts 1/2" square and about 2" long.
Customer is asking for gas nitride to get its anti galling properties and corrosion protection.
Does the gas nitride thru harden or just surface harden?
Do in need to use prehard 4140 material. Or will the nitride work on soft 4140?
Do the part dimensions "grow" or "shrink" during heat treat?
Thanks in advance.
