Screws are widely used, small screws, big world. Different electronic products, electrical products, power products, mechanical equipment products, etc. are not small screws. Everyone knows that screws are made of screw wire. The wire of the screw is divided into iron and stainless steel.
The iron wire is made of iron screws. Generally, the iron wire on the market has 1010.1018.10B21. The iron screws produced by these iron wires need electroplating, and are plated with white zinc, color zinc, white nickel and the like. There are also environmentally friendly plating. Compared with the environmentally friendly color zinc, environmentally friendly blue zinc and so on. Stainless steel wire is made of stainless steel screws. The stainless steel screws produced by this stainless steel wire do not need to be plated, and generally only need to be cleaned, so that the stainless steel screws can be made bright. But there is one point that customers have to have, stainless steel screws also need to be plated, and can be plated with different colors.
Screws are mechanical basic parts and are in great demand. Usually bolts, screws, rivets, etc. are used to ensure safety or generally do not consider the adverse effects of temperature or other dangerous conditions. Commonly used materials are carbon steel, low alloy steel and non-ferrous metals. However, in certain occasions, fastener materials need to meet severe corrosion or high strength conditions, and many stainless steel and ultra-high strength stainless steels have emerged.
Tools/raw materials
Screws, screw wires, and screw wires are available in iron and stainless steel.
Step / method
1. Requirements for the mechanical properties of the screw material, especially the strength. Some screws require a higher strength, so choose the screw material itself to be stronger.
2. Requirements for the corrosion resistance of the material under working conditions. Some screws are used on products with high corrosion resistance, which requires us to choose screw wires with high corrosion resistance.
3. Working temperature requirements for the heat resistance (high temperature strength, oxidation resistance) of the material. Some screws are used in high temperature applications, which requires us to choose screw materials with high temperature resistance.
4. Requirements for material processing performance in terms of production process. In terms of production process, some screws and wires are better processed, some are more difficult, and hardness is harder in all aspects. This requires us to choose the appropriate hardness of the screw material, which is conducive to processing and production.
5. Other aspects, such as weight, price, and purchasing factors must be considered. The weight of the screw itself, the price, the purchase and other factors affect the choice of the screw material, and it is possible to better select the screw material by considering these aspects properly.
Precautions
After comprehensive and comprehensive consideration of these five aspects, the brand, variety, specifications and material standards of the selected fasteners are finally determined.
