1. Requirements for stainless steel screw materials in mechanical properties, especially strength;
2. Work conditions require the corrosion resistance of materials;
3. The operating temperature requires the requirements of heat resistance (high temperature strength, antioxidant properties) of the material;
4. Requirements for material processing performance in production process;
5, other aspects, such as weight, price, procurement, etc. must be considered.
Mechanical behavior
The stainless steel screw is surely, it is definitely made of stainless steel screwdrivers, after the screws of the teeth. The stainless steel screw has many properties to be related to stainless steel.
Considering the performance and tissue of stainless steel, understand the performance of stainless steel. Therefore, it is understood that stainless steel has good mechanical properties such as anti-rust, corrosion resistance, high temperature resistance.
Then the stainless steel screws have these good mechanical properties. As stainless steel material is getting excellent.
The mechanical properties of the stainless steel screws produced by the screw industry are getting better and better. Anti-rust, corrosion resistance, and high temperature high pressure is getting stronger.
Physical properties
The physical performance data contrast of stainless steel and carbon steel, the density of carbon steel is slightly higher than ferrite and martensitic stainless steel, which is slightly lower than the austenitic stainless steel;
The resistivity is incremented by carbon steel, ferrite, martensite, and Austic stainless steel; sorting of the size of the linear expansion is also similar, and the austenitic stainless steel is small and carbon steel;
Carbon steel, ferritic and martial-body stainless steel, the austenitic stainless steel is non-magnetic, but the cold-processed hardening generates a formation of magnetism, and the heat treatment method can be used to eliminate this martensite tissue. Restore its magnetic.
