Stainless steel screws are commonly used accessories in our daily mechanical engineering because they have strong resistance and high corrosion resistance. However, in daily applications, there is also a headache for us, which is that stainless steel screws will corrode under long-term external action. Therefore, the following will explain how to deal with this situation and its hazards.
Compared to other bolts and screws, stainless steel bolts and screws have a wider range of applications in both low and high temperature areas. Therefore, stainless steel screws are becoming increasingly common in practical use. Therefore, stainless steel standard component manufacturers also need to understand this aspect.
The hazards of stainless steel screw failure; Generally, carbon steel and alloy steel bolts fail when there are obvious corrosion products and thinning on their surfaces, while stainless steel screws lose their strength with almost no visible changes on their surfaces, causing serious damage to the structure or equipment. Their failure is more concealed and harmful.
Anti corrosion measures for stainless steel screws;
1. Select qualified stainless steel screws and avoid the formation of gaps in structural design to avoid geometric conditions that are prone to surface deposition;
2. Effectively isolating stainless steel screws from Cl - containing aqueous solution cannot avoid gaps. Through the introduction of the anti-corrosion effect of stainless steel screws, welding or filling the gaps should be used to prevent the entry of aqueous solution;
3. Using stainless steel materials containing high chromium and high molybdenum, especially in low-temperature tank areas, spherical tank areas, and areas with severe stress corrosion, using steel with good corrosion resistance yields better results.
