Question 1 | 1.Why is stainless steel magnetic? |
304 stainless steel belongs to austenitic stainless steel, austenite in the cold working process in part or a small amount of transformation into martensite, martensite is magnetic, so 304 stainless steel is non-magnetic or slightly magnetic. | |
Question 2 | 2. How to identify authentic 304 stainless steel products? |
①Support 304 stainless steel special test potion detection, if not discoloured for the authentic 304 stainless steel | |
② support chemical composition analysis, spectral analysis | |
③ support salt spray test, simulate the actual use of the environment | |
Question 3 | 3. What are the most commonly used stainless steel? |
① 201 stainless steel, suitable for use in dry environments, easy to rust in water | |
② 304 stainless steel, outdoor or wet environment, corrosion resistance and acid resistance | |
③ 316 stainless steel, plus molybdenum, more corrosion resistance and pore erosion resistance, especially for seawater and chemical media |
