Technical Support & Materials Information
Why is stainless steel also magnetic?
304 stainless steel belongs to austenitic stainless steel. During cold processing, austenite may partially transform into martensite, which exhibits magnetic properties, resulting in 304 stainless steel being non-magnetic or slightly magnetic.
How to identify authentic 304 stainless steel products?
  • Use 304 stainless steel specific detection liquid - no color change indicates authentic material
  • Perform chemical composition analysis via spectral analysis
  • Conduct smoke tests to simulate actual use environments
Which kinds of stainless steel are most commonly used?
  • 201 stainless steel - suitable for dry environments, prone to rust in water
  • 304 stainless steel - ideal for outdoor or humid environments with corrosion and acid resistance
  • 316 stainless steel - contains molybdenum for enhanced corrosion resistance, particularly suitable for seawater and chemical media
