Stainless steel heat treatment methods usually include annealing, solution treatment and quenching, etc.
1. Annealing: Stainless steel is heated at high temperature for a period of time and then slowly cooled to eliminate internal stress and improve properties such as plasticity and hardness. The annealing process is divided into complete annealing and partial annealing
2. Solid treatment: Heating stainless steel to the solid solution temperature, keeping it at this temperature for a period of time, and then cooling it quickly to improve the strength, hardness, corrosion resistance, etc. of the alloy.
3. Quenching: Rapidly cool the solution-treated stainless steel to produce a martensite structure and improve the hardness and strength of the stainless steel.
4. Weakening treatment: It is an annealing treatment method that heats stainless steel at a higher temperature and then slowly cools it to reduce the stress and hardness of the material.
These heat treatment methods can be selected and adjusted according to the specific alloying elements, process requirements and use environment of stainless steel to maximize the performance and durability of stainless steel.
