Stainless steel screws are commonly used in our daily mechanical engineering because it has strong resistance, but also has high corrosion resistance, but there are things that make us headache in daily applications. It is the stainless steel screw will appear under long-term external roles. The case of corrosion, so it will be explained to you how to deal with and its harm in this case.
Stainless steel screws compared to other bolts and screws, stainless steel bolts and stainless steel screws are more widely used in low temperatures, high temperatures, and therefore in the actual use of stainless steel screws are increasingly used, so stainless steel standard parts. The manufacturer also needs to understand this.
The harm of stainless steel screws; general carbon steel, alloy steel bolts are failed in the case of significant corrosion products and thinned surfaces, while stainless steel screws will lose strength in their surface, resulting in loss of strength, resulting in structures Or severe damage to the equipment, its failure is more concealed and harmful.
Corrosion and corrosion measures for stainless steel screws;
1. Select a qualified stainless steel screw, and the structural design avoids forming a gap to avoid geometric conditions that are easily surface deposition;
2. Put the stainless steel screw and the CL-containing solution is effectively isolated, and it is not possible to avoid the gap. It is understood by the anti-corrosion effect of stainless steel screws. The gap should be used to fill the gap, and the aqueous solution cannot be entered;
3, using high chromium, high molybdenum, especially in low-temperature tanks, ball tanks, stress corrosion, have better effects.
