Stainless steel screws definition is the use of stainless steel screws material nickel or nickel to eight or more, commercial river 304 stainless steel screws, called SUS304 standard production. At present, major industries use stainless steel screws with increasing frequency. The mechanical properties of stainless steel and carbon steel screws slightly different, more use in a preservative in demanding environments. Surface treatment processing can be achieved without a good anti-corrosion effect. Ferritic stainless steel material classification: 430 ordinary chrome steel, its corrosion resistance and heat resistance is better than 410, magnetic, but it can not be heat strengthened, suitable for heat resistance and corrosion resistance and slightly higher the strength requirements generally stainless steel screws. 316 and 317, which contain alloying elements Mo, Juye 304 stainless steel screws, so their high-temperature strength and corrosion resistance than 18-8 stainless steel high. 321 and 347 type 304 stainless steel screws, 321 contain more stable alloying elements Ti, 347 type containing Nb, thereby increasing the resistance to intergranular corrosion of materials. Not annealed or stainless steel fasteners in 420 ~ 1013 ℃ after serving applies to welding.
