没有做过这个材料，资料上查到的工艺是：
Heat Treatment
Condition A
(Solution Treated or Annealed): Heat to 1500/1550 °F, and cool rapidly. Water quenching is preferred for small sections. Custom 455 stainless will normally be supplied from the mill in the
annealed condition, ready for the one-step hardening treatment.
Condition H 900, H 950, H 1000, H 1050
(Precipitation or Age Hardened): The high strength levels

固溶后硬度是31HRC左右；
H900时效硬度在48HRC左右；
H1000是45HRC左右；
H1050是40HRC左右。
