Causes & Anti-rust Solutions for Stainless Steel Fasteners

Stainless steel fasteners may get rusty under humid and salt fog environment, proper processing can effectively avoid corrosion.

1. Common rust inducing factors

Impure raw material, scrap iron residue, damp storage and carbon steel friction contact lead to rust spots.

2. Passivation anti-rust treatment

Passivation treatment forms protective film on screw surface to improve salt spray resistance.

3. Storage and construction tips

Sealed moisture-proof storage, adopt 316 stainless steel for coastal engineering projects.
