Hot forming temperature: 1150-850oC.
Machining is done prior to carburizing to within as close a tolerance as possible. Finish machining, after heat treatment and/or carburizing, should be at a minimum so as not to impair the hardened case of the part. Machining may be done by conventional means prior to heat treatment - after carburizing machining is usually limited to grinding.
The alloy may be welded by conventional methods, usually gas or arc welding. Preheating at 200oC is beneficial and subsequent heating after welding is recommended - consult the approved weld procedure for the method used.
The alloy may be cold worked in the annealed condition by conventional methods. Cold working, as with machining, should be done to as close a tolerance as possible before heat treatment or carburizing.
