Common Questions and Answers:
 

Q: Why is 304 stainless steel wire corrosion-resistant?

A: Chromium forms a dense chromium oxide (Cr₂O₃) passivation film, which isolates the metal from contact with corrosive media. Nickel enhances the stability of the passivation film and improves resistance to acids and alkalis.

Q: Is 304 stainless steel wire magnetic?

A:It is typically non-magnetic at room temperature (austenitic structure), but cold working (such as drawing or stamping) may produce a small amount of martensitic structure, resulting in slight weak magnetism, which does not affect usability.

Q: How is the high-temperature resistance of 304 stainless steel wire?

A: It can withstand short-term temperatures up to 800°C, and long-term use is recommended not to exceed 650°C. It is suitable for scenarios such as automotive exhaust systems and industrial furnaces.
