When heat treating precipitation hardening stainless steel careful consideration should be given to heat treatment temperatures, including rate of heating, cooling and soaking times etc. as these may vary due to factors such as the shape and size of each component. Other considerations during the heat treatment process include the type of furnace, quenching medium and work piece transfer facilities. Please consult your heat treatment provider for full guidance on heat treatment of precipitation hardening stainless steels.
