The phenomenon of surface marks refers to the occurrence of wire-mounted or point-shaped pit marks on the surface of 304 stainless steel after deep processing or grinding of processed products.
Reason: There are foreign objects on the surface and mold surface, and there are scars on the surface of the blanking pad.
Countermeasures: Remove foreign bodies, scars, and orange peel by fully grinding before processing.
The orange peel phenomenon refers to the phenomenon that the surface of 304 stainless steel moldings has a shape like orange peel under grinding or other conditions.
Reason: Insufficient grinding, the larger the processing, the more serious the orange peel, the coarse grains of the raw materials, and the softening of heat treatment.
Countermeasures: Fully grind the deep-processed products, select suitable heat treatment conditions, and control the grain size of the raw materials.
