How to choose screw raw materials

2023-06-13

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 influence 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 as the times require.

1
Requirements for screw materials in terms of mechanical properties, especially in terms of strength. Some screws require higher strength, so choose the screw material itself with higher strength.

2
The requirements of working conditions on the corrosion resistance of materials. Some screws are used on products with strong corrosion resistance, which requires us to choose screw wires with strong corrosion resistance.

3
The requirements of the working temperature on the heat resistance (high temperature strength, oxidation resistance) of the material. Some screws are used in high temperature operation, which requires us to choose screw materials with high temperature resistance.

4
The requirements of the production process on the processing performance of the material. In terms of production technology, some screw wires are easier to process, and some are more difficult, and the hardness is harder in all aspects. This requires us to choose the screw material with appropriate hardness, which is conducive to processing and production.

5
Other aspects, such as weight, price, procurement and other factors must be considered. The weight of the screw itself, price, purchase and other factors affect the selection of screw materials. Only by properly considering these aspects can a better choice of screw materials be possible.

END
Precautions
After comprehensive and comprehensive consideration of these five aspects, the grade, variety, specification and material standard of the selected fasteners are finally determined.
