Stainless steel fastener material related knowledge

Fasteners are used stainless steel as the material, can say whether it has great advantage in all aspects of manufacturing, use or processing, so although fasteners for stainless steel for the high cost of material itself, life cycle is relatively short, but in the solution of a fastener, but still belongs to the more savings.
Stainless steel magnetic problem of fasteners
If using stainless steel fasteners as main material, but also understand the problems about magnetic stainless steel itself. Stainless steel is generally considered not magnetic, but in fact the austenitic material through a certain process, is likely to be a certain magnetism, but if you think that magnetism is to judge the quality of stainless steel fasteners standard is not accurate.
Fasteners in the selection, the stainless steel material with magnetic and cannot prove that the level of quality, in fact some Cr Mn stainless steel is not magnetic stainless steel. The use of stainless steel fasteners in Cr Mn stainless steel and is not a substitute for 300 series stainless steel, especially in high corrosive medium environment is even more so.
The use of nickel fasteners
In the use of stainless steel fasteners for the material in the process, the use of ever more dependent on the nickel element, but in the case of Ni global prices, fastener prices are also affected by the. Fastener manufacturing enterprises in order to mitigate cost pressures, improve the fastener competition ability, especially in finding alternative materials, production of stainless steel fasteners low nickel type.
