Stainless steel standard fasteners have their own requirements for production materials.Most stainless steel materials can be made into steel wires or rods for fastener production, including austenitic stainless steel, ferritic stainless steel, martensitic stainless steel, and precipitation hardening stainless steel.It is recommended that the selection of stainless steel materials is mainly considered from the following 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 requirements of the working temperature on the heat resistance of the material (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.
After comprehensive consideration of these five aspects, suitable stainless steel materials are selected according to relevant standards.
