How to choose screw materials?
Screws are basic mechanical parts with high demand. Generally, bolts, screws, and rivets, etc., don't usually consider the impact of temperature, harsh environments, or other hazardous working conditions to ensure safety. Commonly used materials include carbon steel, low alloy steel, and non-ferrous metals. However, in specific situations, fastener materials need to meet the conditions of severe corrosion or high strength, leading to the development of many stainless steels and ultra-high-strength stainless steels.
1. Requirements for the mechanical properties of screw materials, especially strength. Some screws require higher strength, so screw materials with higher inherent strength are chosen.
2. Requirements for the corrosion resistance of the material under operating conditions. Some screws are used in products with strong corrosion, requiring the selection of screw wire with strong corrosion resistance.
3. Requirements for the heat resistance of the material (high-temperature strength, oxidation resistance) under working temperature. Some screws are used in high-temperature operations, requiring the selection of screw materials with high high-temperature resistance.
4. Requirements for the processing performance of the material in terms of production processes. Some screw wires are easier to process in production, while others are more difficult, with varying hardness. This requires selecting screw materials with appropriate hardness for easier processing and production.
5. Other aspects, such as weight, price, and procurement factors, should also be considered. The weight, price, and procurement of the screws themselves affect the choice of screw materials. Considering these aspects appropriately can lead to better screw material selection.
