Usually used as a decorative tube plate is austenitic stainless majority of 304, in general, is a non-magnetic or weakly magnetic, but the chemical composition fluctuations caused by smelting or processing may occur in different magnetic state, but can not be considered counterfeit or substandard combination stainless steel screw, which is what causes it? Austenitic mentioned above are non-magnetic or weakly magnetic, and martensite or ferrite is magnetic, due to improper segregation smelting or heat, can cause a small amount of martensite in austenitic 304 stainless steel or ferrite body tissue. Thus, the 304 will carry the weak magnetism. In particular, proposed that magnetic caused due to the above reasons Weihai 304 stainless steel screw combination with other materials Jining stainless steel screw combinations, such as 430, magnetic steel is absolutely not the same level, ie 304 magnetic steel Always show is weakly magnetic. This tells us that if the weak magnetic stainless steel or entirely without magnetic stainless steel combination screws Yantai, should determine for 304 or 316; if the magnetic steel of the same, showing a ferromagnetic, because discrimination is not 304.
