FAQ
Common heat treatment methods for stainless steel round steel 321 include annealing, solution treatment, quenching and stress relief annealing.
1. Annealing: Heating to 800-900, then slowly cooling to room temperature to eliminate stress and improve the toughness and plasticity of the material.
2. Solution treatment: Heating stainless steel round steel 321 to a temperature range of 950-1050, then rapidly cooling to dissolve alloy elements and carbides, and improve the strength and heat resistance of the material.
3. Quenching: Heating stainless steel round steel 321 to the solution treatment temperature range, then rapidly cooling to increase the hardness and strength of the material.
4. Stress relief annealing: Heating stainless steel round steel 321 to a temperature range of 650-750, then slowly cooling to room temperature to eliminate internal stress in the material and improve its stress corrosion resistance.
