Stainless steel screws selection principles: choice of stainless steel materials, mainly from the following five aspects to consider. 1, Material Stainless steel screw fasteners in mechanical properties, especially the strength requirements; 2, a job conditions on the material aspects of corrosion resistance requirements; 3, the working temperature of the heat resistance of the material (high temperature strength oxidation resistance) requirements; 4, the production process for material processing performance requirements; 5, other aspects, such as weight, price, purchase, and many other factors must be considered Jining 316 and 317 stainless steel fasteners, they Linyi contain alloying elements Mo stainless steel fasteners, so their high-temperature strength and corrosion resistance than 18-8 stainless steel high. Type 321 and Type 347, Type 321 alloy containing more stable elements Ti, 347 type containing Nb, thereby increasing the resistance to intergranular corrosion of materials. Not annealed or stainless steel pieces at 420 ~ 1013 ℃ after serving apply to welding.
