SKF 388K steel
SKF 388K steel
(OP)
Hi All,
What are the other equivalent standards for 388K? Is this material forgeable?
Recently I forged this steel and ended up with cracks in some of the parts.
I would appreciate if any of you can help.

If you have access to ASM Handbook, Vol 1 it contains an excellent write-up on this material, including recommended forging temperatures. It is recommended to heat this material to 2250 deg F max, and finish forging at or above 1800 deg F. Slow cool in a furnace or insulating medium.
