416 stainless steel bars have higher tensile strength, yield strength and elongation than ordinary stainless steel. In addition, the low-temperature toughness can maintain good mechanical properties at lower temperatures. 416 stainless steel bars have excellent corrosion resistance and can maintain strong stability in differing corrosive environments. This is mainly attributed to the high content of chromium, which can integrate with oxygen to create a dense oxide film on the surface to prevent the metal inside from being eroded. 416 stainless steel bars are widely used in fields including petroleum, chemical industry, pharmaceutical, food, environmental protection for its satisfying corrosion resistance and mechanical properties.
