Typically, carbon steel heads are hot formed at
1,650°F (899°C). Stainless steel heads are hot
formed at approximately 1,900°F (1,038°C).
Chromium molybdenum steel heads are usually
hot formed at 1,650°F (899°C) and tempered at
1,350°F (732°C).
Clad heads are formed at temperatures suitable
to the material. Various forming temperature
requirements and additional heat treatments can
be accommodated upon request.
