Forging Temepratures
Forging Temepratures
(OP)
Can anyone advise the forging temperature range of ASTM A182F91 (UNS K90901) steel?
This is a 9% Cr,1% Mo, 0.2% V steel

RE: Forging Temepratures
Large sections should be preheated to 1200/1400°F (649/760° C) or heated slowly in the furnace. Initial forging should be conducted in the 1900/2150°F (1038/1177°C) range. Billets should not be finish forged below 1600/1650°F (871/899°C). Avoid long heating cycles as this can result in excessive decarburization. Forgings should be cooled slowly and annealed or tempered as soon as possible after reaching room temperature. Do not harden without performing an intermediate anneal or preheating in the temperature range 1200/1400°F (649/760°C).
RE: Forging Temepratures
As far as forging temperature, the information above is an acceptable temperature range for hot working. Forgings can be left in the hot worked condition BUT must be heat treated separately to achieve the desired martensitic microstructure using sufficient cooling - quenching and tempering.
