Commonly used with the material of carbon steel, low alloy steel and non-ferrous metals. But in particular cases, fastener materials need to meet serious corrosion or high intensity conditions, there are many stainless steel and high strength stainless steel arises at the historic moment.

Fasteners is mechanical foundation pieces, in great demand, usually bolts and screws, rivets, etc to ensure safety or generally don't have to consider the influence of the temperature of the bad environment or other dangerous working conditions.

Material select principle, choice stainless steel materials mainly from the following five aspects consider.

1 and the production process of material processing performance requirements;

2, the work of the material heat-resisting temperature performance (high temperature strength, oxidation resistance) requirements;

3 and other aspects, such as weight, price, purchasing the factors to consider.

4, working condition of the material corrosion performance requirements;

5, to the fasteners materials in mechanical properties, especially in terms of the requirements of strength;

Through five aspects of this comprehensive, integrated consideration, the final determination of the brand, choose fasteners varieties and specifications, material standards.
