Magnetic Steel Fasteners Manufacturer

Stainless steel is a popular material in fastener production thanks to its excellent corrosion resistance and durability. Magnetic stainless steel fasteners, such as SS 410, SS 430, SS 420, and SS 439, are particularly sought-after for their unique properties.

SS 410 is martensitic stainless steel with 11.5% chromium content, making it highly corrosion-resistant. These fasteners have strong scaling resistance at temperatures up to 1200°F.
SS 430 fasteners are known for their high resistance to pitting and crevice corrosion, as well as their formability and mechanical qualities. They can also withstand nitric acid and are suitable for specific chemical applications.

Meanwhile, SS 420 fasteners resist freshwater, mild acids, alkalis, air, and food. They have a smooth surface finish and provide excellent results.

Finally, SS 439 fasteners have 17% chromium content, making them highly corrosion-resistant in mildly corrosive conditions. They are also resistant to oxidation at high temperatures and do not suffer from chloride stress corrosion cracking since they are ferritic stainless steel.
