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  |
