Summary : Stainless steel is the short name for stainless acid resistant steel. As we known, stainless steel 304, 316, 316L are three commonly applied stainless steel material, do you know the difference? Please find below sheet.

Stainless steel is the short name for stainless acid resistant steel. Stainless steel is notable for its corrosion resistance, and it is widely used for food handling and cutlery among many other applications. Stainless steel does not readily corrode, rust or stain with water as ordinary steel does. However, it is not fully stain-proof in low-oxygen, high-salinity, or poor air-circulation environments. There are various grades and surface finishes of stainless steel to suit the environment the alloy must endure. Stainless steel is used where both the properties of steel and corrosion resistance are required. As we known, stainless steel 304, 316, 316L are three commonly applied stainless steel material, do you know the difference? Please find below sheet.
