Stainless steel screws selection principles: choice of stainless steel materials, mainly from the following five aspects to consider. 1, the material for stainless steel screws in mechanical properties, specifically strength requirements; 2, working conditions on the corrosion resistance do aspect material requirements; 3, the working temperature of the material of the heat resistance (high temperature strength, oxidation resistance requirements) aspects; 4, the production process for material processing performance requirements; 5, other aspects, such as weight, price, purchase, and many other factors must be considered in particular to make is within Yantai stainless steel hex screws, caused due to the above reasons magnetic 304 stainless steel, stainless steel and other materials inside the stainless steel hex screws, such as 430, magnetic steel is absolutely not the same level, ie 304 steel magnetic always shows weak magnetism. This tells us Weihai stainless steel hex screws, if weakly magnetic stainless steel or completely without internal magnetic Jining stainless steel hex screws, should be determined as 304 or 316; if the magnetic steel of the same, showing a ferromagnetic, because it is determined not 304. Within Heze stainless steel hex screws, stainless steel hex screws, Jinan Road ground is provided by Jinan Daoqin Trading Company.
