Introduction to the process of aging stainless steel: After selecting stainless steel, first carry out shading treatment on its surface. You can etch the shading process on the surface to give the stainless steel a rich sense of unevenness and unevenness. Then coat the surface of the stainless steel with a copper layer. After the base color is plated, the surface is blackened and oxidized with liquid medicine to make the surface of the stainless steel rich in color. During this period, a high-temperature heat treatment process is also needed, and the process is continuously recycled until the desired effect is achieved. Finally, a fingerprint-free oil treatment process is carried out.
