Stainless steel is a kind of alloy steel, with smooth surface, high weldability, corrosion resistance, polishing, heat resistance, corrosion resistance and other characteristics. It is widely used in various industries and is an important material in modern industry. Stainless steel is divided into stainless steel, iron oxygen stainless steel, Martengsitt stainless steel and duplex stainless steel by structural state.

Product advantage

1. Environmental protection: It can effectively reduce environmental pollution.

2. Corrosion resistance: stain resistance, acid resistance, corrosion resistance, wear resistance, no radioactivity.

3. Surface cleaning: the surface of the product is smooth and compact, not easy to be polluted by dust, with good self-cleaning.

4. Easy maintenance: Easy to repair minor damage.
