Material properties of stainless steel fasteners

DataTime:[2018-6-25]

Stainless steel fastener standard parts are made of stainless steel wire as raw material, and then processed according to the related working procedure of pier. At present, stainless steel fasteners have been widely used, because the performance advantages of their various aspects are very obvious. Below are the advantages of these fasteners.
The first is the high temperature resistance of stainless steel fasteners. Because of its hardness and anti oxidation ability of stainless steel fasteners made of very strong, have high antioxidant properties, and also can work under high temperature, and will not suffer too much influence in high temperature environment, even if the stainless steel fasteners and passivation after manufacturing, the high temperature performance will be better.
Stainless steel fasteners have high resistivity. Specifically, the resistivity of stainless steel fasteners is five times higher than that of carbon steel. The test shows that the higher the temperature is, the expansion coefficient of the stainless steel fastener will be improved to a certain extent.
The capacity of stainless steel fasteners to withstand load is relatively moderate, though it can not be compared with high-strength bolts, but it is also enough to meet daily needs, and its price is much cheaper.
The mechanical properties of stainless steel fasteners are mainly influenced by the mechanical properties of the stainless steel wires used, such as hard rust and strong corrosion resistance. And with the rapid development of stainless steel materials, the mechanical properties of stainless steel fasteners will become stronger and stronger.
In the selection of fasteners, stainless steel material has no magnetism in fact does not show that its quality is good or bad, actually some Cr Mn stainless steel is also not magnetic, and austenitic stainless steel after certain processing technology, it may produce a certain magnetism, so to have no magnetic to judge the quality of stainless steel fasteners is not accurate. Stainless steel fastener material Cr Mn stainless steel can not replace the 300 series stainless steel fasteners, especially when the working environment is highly corrosive.
In general, whether in manufacturing, application or processing, fasteners are made of stainless steel as raw materials are of considerable advantage, although the relatively high cost of stainless steel materials, but its use is actually longer cycle, fastener materials in many environments, is actually very cost-effective.
