The anti-corrosion mechanism of stainless steel is that alloy elements form a dense oxide film, which isolates oxygen contact and prevents further oxidation. Therefore, stainless steel is not truly "rustproof." 304 stainless steel is a widely used stainless and heat-resistant steel on the market.

304 stainless steel angle bars are mainly divided into equal leg stainless steel angle bars and unequal leg stainless steel angle bars. The unequal leg stainless steel angle bars further categorize into unequal leg equal thickness and unequal leg unequal thickness types. They are primarily used in food processing equipment, chemical equipment, and more.
