Stainless steel fastener use stainless steel as raw materials. Stainless steel fastener has four properties.
1. High temperature resistance. For high hardness, the fastener has strong oxidation resistance. It cannot work under high temperature and cannot be interfered by high temperature. If the fastener is passivated after being made out, the temperature resistance will be better.
2. Physical properties. Stainless steel fastener has higher specific resistance. The specific resistance of stainless steel is higher than that of carbon steel by five times. Standard parts have an expansion factor. Through experiment, if the temperature is higher, the expansion factor of stainless steel fastener will be improved definitely.
3. Stress capacity. Stainless steel fastener can endure moderate stress. Although it cannot be compared favorably with high strength bolt, the fastener can still meet the common requirements.
4. Mechanical properties. High rust resistance and corrosion resistance have close relationship with the features of stainless steel. For standard parts developing constantly, mechanical properties of stainless steel fastener will be enhanced further.
