Common questions about stainless steel:
Q: Why is stainless steel magnetic?
A: 304 stainless steel belongs to austenitic stainless steel. Austenite is partially or slightly transformed into martensite during cold working. Martensite is magnetic, so stainless steel is nonmagnetic or weakly magnetic.
Q: How to identify authentic stainless steel products?
A: 1. Support stainless steel special potion test, if it does not change color, it is authentic stainless steel.
2. Support chemical composition analysis and spectral analysis.
3. Support smoke test to simulate the actual use environment.
Q: What are the most commonly used stainless steels?
A: 1.SS201, suitable for use in dry environment, easy to rust in water.
2.SS304, outdoor or humid environment, strong resistance to corrosion and acid.
3.SS316, molybdenum added, more corrosion resistance, especially suitable for seawater and chemical media.
Five advantages of stainless steel:
1. High hardness, no deformation ----- The hardness of stainless steel is more than 2 times higher than that of copper, more than 10 times higher than that of aluminum, the processing is difficult, and the production process is complicated.
2.Durable and non-rusty ---- made of stainless steel, the combination of chrome and nickel creates a layer of anti-oxidation on the surface of the material, which plays the role of rust.
3.Environmentally friendly, non-toxic and non-polluting ------- Stainless steel material has been recognized as sanitary, safe, non-toxic and resistant to acids and alkalis. It is not released to the sea and does not pollute tap water.
4. Beautiful, high-grade, practical -------- Stainless steel products are popular all over the world. The surface is silver and white. After ten years of use, it will never rust. As long as you wipe it with clean water, it will be clean and beautiful, as bright as new.
