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

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
