Commonly used heat treatment processes for martensitic steels include annealing, stress relief, quenching and tempering.
What is the heat treatment process for austenitic stainless steel?
Answer: 1Cr18Ni9Ti is a typical (18-8 type) chromium-nickel austenitic stainless steel. Since 18-8 stainless steel basically maintains a single austenite structure in the solid state, there is no a→γ in the process of heating and cooling. Allotropic transformation, so in addition to precipitation hardening austenitic stainless steel, it is impossible to strengthen the steel by heat treatment. General 18-8 austenitic steel can only be strengthened by cold deformation.
Commonly used heat treatments for 18-8 steel include stress relief treatment, solution treatment, sensitization treatment, stabilization treatment and heat treatment to eliminate σ phase.
