Selection principle of stainless steel wire for fasteners
Most stainless steel materials can be made into steel wires or bars for fastener production, including austenitic stainless steel, ferritic stainless steel, martensitic stainless steel, and precipitation hardening stainless steel. Regarding the selection of stainless steel wire for fasteners: Fasteners 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, on certain occasions, fastener materials need to meet severe corrosion or high-strength conditions, and many stainless steels and ultra-high-strength stainless steels have emerged.
After comprehensive and comprehensive consideration of these five aspects, the grades, varieties, specifications and material standards of the fasteners are finally determined.
The choice of stainless steel materials is mainly considered from the following five aspects.
1. Requirements for fastener materials in terms of mechanical properties, especially strength.
2. The requirements of working conditions on the corrosion resistance of materials.
3. The working temperature requires the material's heat resistance (high temperature strength, oxidation resistance).
4. Requirements for material processing performance in terms of production technology.
5. Other aspects, such as weight, price, and purchasing factors must be considered.
