?Compared with other bolts and screws, stainless steel bolts and stainless steel screws are more widely used in low temperature and high temperature areas, so stainless steel screws are becoming more and more widely used in practical use.
1. The damage of stainless steel screws.
Carbon steel and alloy steel bolts generally fail in the case of obvious corrosion products and thinning on the surface, and the stainless steel screws will lose strength when they can hardly see any change on the surface, causing serious damage to the structure or equipment, and its failure is more concealed and harmless.
Two, corrosion prevention measures of stainless steel screws
1. Choose qualified stainless steel screws to avoid cracks in the structural design and avoid the geometric conditions that cause surface deposition easily.
2, the stainless steel screw and Cl- containing water solution can be isolated effectively, and the gap can not be avoided. Through the corrosion prevention of stainless steel screws, it is necessary to use welding or fill the gap so that the water solution can not enter.
3, the use of high chromium and molybdenum stainless steel materials, especially in the low-temperature tank area, spherical tank area, stress corrosion serious area with good corrosion resistance steel, the effect is better.
