Why is stainless steel magnetic?
304 stainless steel belongs to austenitic stainless steel. Part or a small amount of austenite is transformed into martensite during cold working. Martensite is magnetic, so 304 stainless steel is non-magnetic or micro magnetic.
How to identify authentic 304 stainless steel products?
① support 304 stainless steel special detection liquid medicine detection, if not discolored, it is authentic 304 stainless steel.
② Support chemical composition analysis and spectral analysis.
③ Support smoke test and simulate the actual use environment.
What are the most commonly used types of stainless steel?
① 201 stainless steel, suitable for use in dry environment, easy to rust in water.
② 304 stainless steel, outdoor or humid environment, strong corrosion and acid resistance.
③ 316 stainless steel, molybdenum added, more corrosion and pitting resistance, especially suitable for seawater and chemical media.
