High hardness, no deformation ----- The hardness of stainless steel is more than 2 times higher than that of copper, more than 10 times higher than that of aluminum, the processing is difficult, and the production process is complicated. ☆ 2.Durable and non-rusty ---- made of stainless steel, the combination of chrome and nickel creates a layer of anti-oxidation on the surface of the material, which plays the role of rust. ☆ 3.Environmentally friendly, non-toxic and non-polluting ------- Stainless steel material has been recognized as sanitary, safe, non-toxic and resistant to acids and alkalis. It is not released to the sea and does not pollute tap water. ☆ 4. Beautiful, high-grade, practical -------- Stainless steel products are popular all over the world. The surface is silver and white. After ten years of use, it will never rust. As long as you wipe it with clean water, it will be clean and beautiful, as bright as new.
