Description of Forged Alloy Steel Bar SAE***0 1.***3 **0M*0
One of the most popular and widely used carborizing steels available. *0MoCr4 is a hardenable chromium, molybdenum, nickel low alloy steel often used for carburizing to develop a case-hardened part. This case-hardening will result in good wear characteristics.

Applications of Forged Alloy Steel Bar SAE***0 1.***3 **0M*0
Gears, shafts and other applications where a hard carborized case and a tough core are desired.

Physical properties (avarage values) at ambient temperature

Forging of Forged Alloy Steel Bar SAE***0 1.***3 **0M*0
Hot forming temperature: *******0oC.
Machinability
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.
