Q&A

1. Why is stainless steel also magnetic?
304 stainless steel belongs to austenitic stainless steel, austenite in the cold processing process is partially or a small amount of martensite martensite is magnetic, so 304 stainless steel is non-magnetic or micro-magnetic. Specifically, you can search why 304 stainless steel contains magnetism.

2. How to identify authentic 304 stainless steel products
① Support 304 stainless steel special detection liquid detection, if not discolored for authentic 304 stainless steel.
② Support chemical composition analysis spectral analysis.
③ Support smoke test to simulate the actual use environment.

3. Which kinds of stainless steel are most commonly used?
1.201 stainless steel, suitable for use in dry environment, it is easy to rust in water.
2304 stainless steel, outdoor or humid environment, corrosion and acid resistance.
③316 stainless steel, plus molybdenum, more corrosion resistance and corrosion resistance, especially suitable for seawater and chemical media
