Stainless steel counter refrigerator stainless steel surface work hardening

Stainless steel surface work hardening is a process that significantly improves the hardness of the material surface layer by physical or mechanical means, while maintaining or slightly sacrificing the toughness of the core. This technology is widely used in stainless steel counter refrigerators and other stainless steel products that require high-strength and high-wear-resistant surfaces.
Specific methods for stainless steel surface work hardening
Cold rolling:
Cold rolling is one of the common methods for stainless steel surface work hardening. Through the cold rolling process, the stainless steel sheet is subjected to strong plastic deformation at room temperature, the surface layer grains are refined, and the dislocation density is increased, thereby significantly improving the surface hardness. The stainless steel sheet after cold rolling not only increases in hardness, but also has a smoother surface, which is conducive to subsequent processing and use.
Shot peening:
Shot peening is a process that uses high-speed hard particles to hit the stainless steel surface, causing it to produce plastic deformation and residual compressive stress. This treatment method can significantly improve the hardness and fatigue resistance of the stainless steel surface, while enhancing the surface's corrosion resistance. The effect of shot peening is related to factors such as the material, size, speed and spray angle of the sprayed particles.
Rolling: Rolling is a process that uses rolling tools to partially or completely press the surface of stainless steel. During the rolling process, the stainless steel surface is subjected to strong plastic deformation, the grains are refined, and the dislocation density is increased, thereby achieving work hardening. Rolling can not only improve the hardness and wear resistance of the stainless steel surface, but also improve its surface roughness and flatness.
