About stainless steel
Why is 304 stainless steel magnetic?
304 stainless steel belongs to austenitic stainless steel. A part or a small amount of austenitic stainless steel is transformed into martensite during the cold working process, and martensite is magnetic, so 304 stainless steel is non-magnetic or weakly magnetic.
How to identify authentic stainless steel products?
1. Support stainless steel special detection potion detection, if it does not change color, it will be authentic stainless steel.
2. Support chemical composition analysis and spectral analysis.
3. Support salt spray test to simulate actual use environment.
What are the most common types of stainless steel?
1. 201 stainless steel, suitable for use in a dry environment, easy to rust in contact with water.
2. 304 stainless steel, suitable for outdoor or humid environment use, strong corrosion and acid resistance.
3. 316 stainless steel is more resistant to corrosion and pitting, especially suitable for sea water and chemical media.
Note: in order to avoid measurement errors, please try to use vernier calipers to measure.
