1. Stainless steel does not rust because the content of chromium and nickel is very high 2. Stainless steel has a bright and appearance without electroplating 3. Austenitic stainless steel is non-magnetic and does not attract magnets. However, a small part of the sphere produced weak magnetism that could not be removed during the manufacturing process 4. The anti-corrosion performance is very good and can be used in harsh environment 5.304 stainless steel has the characteristics of no rust, stable chemical properties, beautiful corrosion resistance, high-grade, no secondary pollution, long service life and no release of toxic substances during use. Therefore, it is known as a green and environmentally friendly material with good comprehensive performance in the new century
