Stainless steel screws have excellent corrosion

Stainless steel screws have excellent corrosion resistance due to their material properties. They can remain stable in wet and corrosive environments, which is particularly suitable for the chemical industry, marine engineering, and food processing. In addition, stainless steel screws have high strength, tensile strength is usually between 500-800MPa, yield strength between 300-500MPa, which makes it can remain stable when subjected to large tensile force.

SUS304 stainless steel screws: this screw has good corrosion resistance and moderate work hardening rate, suitable for general cold interprocessing and stretching, widely used in construction, home improvement, chemical industry and other fields

SUS316 stainless steel screws: with better resistance to pore corrosion and cold workability, suitable for more corrosive environments, such as chemical and ocean engineering

Duplex stainless steel D8-80 screws: a blend of austenitic and ferritic advantages of the two phases, with excellent corrosion resistance and high tensile strength, suitable for harsh working conditions.

The difference between stainless steel screws and carbon steel screws

Corrosion resistance: stainless steel screws have excellent corrosion resistance due to its internal chromium formation of the protective layer, can remain stable in wet and corrosive environments, while carbon steel screws require additional anti-corrosion treatment or the use of higher-grade materials.

Strength: Carbon steel screws typically exhibit higher hardness and strength for high loads and stress environments, while stainless steel screws are lower in strength but adequate in most applications.
