How to choose the screw material?

How to choose the screw material?Glued screws for you to answer the question.

Screws are mechanical basic parts, the demand is great, usually bolts, screws, rivets and so on in order to ensure safety or generally do not have to consider the effect of temperature harsh environment or other dangerous working conditions.Commonly used materials are carbon steel, low alloy steel and non-ferrous metals.However, in specific occasions, fastener materials need to meet the conditions of severe corrosion or high strength, there are many stainless steel and ultra-high strength stainless steel came into being.

1, the screw material in terms of mechanical properties, especially the strength requirements.Some screws need higher strength, then choose the screw material itself higher strength.

2, working conditions on the corrosion resistance of the material requirements.Some screws used in the corrosive properties of the product above, which requires us to choose a strong corrosion resistance of the screw wire.

3, the working temperature of the material's heat resistance (high-temperature strength, oxidation resistance) requirements.Some screws used in high-temperature operating conditions, which requires us to choose high-temperature performance screw material.

4, the production process on the material processing performance requirements.In the production process, some screws and wires are better processed, some are more difficult, the hardness of all aspects of the hard.This requires us to choose the appropriate hardness of the screw material, conducive to processing and production.

5, other aspects, such as weight, price, procurement factors should be considered.The weight of the screw itself, price, procurement and other factors affect the choice of screw material, proper consideration of these aspects may be a better choice of screw material.
