Description :
Forging, upsetting and other operations relating to 254-SMO material can be performed at 982°C - 1149°C (1800°F - 2100°F). We always maintain the temperature to not exceed this range as it would result in scaling and reduction in the workability of the material. To re-attain maximum corrosion resistant properties, we do not perform post-process annealing.The high alloy additions ensure that it has a strength nearly twice that of 3xx austenitic stainless steels. It retains excellent ductility and toughness at both elevated and sub-zero temperatures. It can generally be formed and welded in the same way as other 3xx alloys, but the high work hardening rate means that machining may require slower speeds / more power.
