How to choose screw material?
How to choose the screw material? Glue screw small make up for you to answer.
Screws are mechanical basic parts and are in great demand. Usually bolts, screws, rivets, etc. are used to ensure safety or generally do not need to consider the impact of temperature in harsh environments or other dangerous working conditions. Commonly used materials are carbon steel, low alloy steel and non-ferrous metals. However, in certain occasions, fastener materials need to meet the conditions of severe corrosion or high strength, and many stainless steels and ultra-high strength stainless steels have emerged.
1. Requirements for screw materials in terms of mechanical properties, especially strength. Some screws need higher strength, so choose the screw material itself with higher strength.
2. Requirements of working conditions on corrosion resistance of materials. Some screws are used in products with strong corrosion performance, which requires us to choose screw wires with strong corrosion resistance.
3. The requirements of the working temperature on the heat resistance of the material (high temperature strength, oxidation resistance). Some screws are used in high temperature operation, which requires us to choose screw materials with high temperature resistance.
4. Requirements for material processing performance in terms of production process. In the production process, some screws and wires are better processed, some are more difficult, and the hardness is harder in all aspects. 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, appropriate consideration of these aspects may be better choice of screw material.
