Compared to other bolts and screws, a stainless steel bolts and stainless steel screws in both low and high temperature location, its broader range of applications, and therefore stainless steel screws are also increasingly being widely used in practical use.

    First, the stainless steel screws failure hazards.

    General carbon steel, alloy steel bolt is on its surface a clear case of thinning corrosion products and failure, and the case of stainless steel screws will hardly see any change in its surface no loss of strength, causing serious damage to the structure or equipment, Its failure is more covert and harmful.

    Second, anti-corrosion measures stainless steel screws

    1, the selection of qualified stainless steel screws, avoiding the formation of cracks in structural design, to avoid prone deposited on the surface geometry;

    2, the stainless steel screws and an aqueous solution containing Cl- for effective isolation, the gap can not be avoided by the introduction of stainless steel screws corrosion protection is understood that the gap should be filled by welding or real, so water can not enter;

    3, the use of high chromium, high molybdenum stainless steel materials, in particular the use of good corrosion resistance in low temperature steel tank, tank area, stress corrosion serious area, the better.
