Application
Stainless steel has unique characteristics such as unique strength, high abrasion resistance, superior anti-corrosion performance and resistance to rust. Therefore, it is widely used in industry, food machinery, mechanical and electrical industry, household appliance industry, home decoration and finishing industry. The development prospect of stainless steel application will be more and more broad, but the development of stainless steel application largely depends on the development of its surface treatment technology.
