Using stainless steel as the material for fasteners offers significant advantages throughout the manufacturing, use, and handling processes. Although the cost of fasteners made from stainless steel is higher and their service life is relatively shorter, they still remain a more cost-effective option within fastener solutions.
Problem with Stainless Steel Fasteners' Magnetism
Fasteners made primarily of stainless steel require an understanding of the material's magnetic properties. Generally, stainless steel is considered non-magnetic; however, after certain processing techniques, Austenitic series materials can exhibit magnetic properties. Nonetheless, assuming that magnetism is a standard for evaluating the quality of stainless steel fasteners is inaccurate.
When selecting fasteners, the presence or absence of magnetism in stainless steel does not indicate its quality level. In fact, some chrome-manganese stainless steels are non-magnetic. Chrome-manganese stainless steel in stainless steel fasteners cannot replace the use of 300 series stainless steel, especially in high medium corrosive environments.
The use of nickel in fasteners
During the production process of fasteners using stainless steel, there has been a reliance on nickel usage. However, with the global surge in nickel prices, fastener costs have been significantly affected. To alleviate cost pressures and enhance competitiveness, fastener manufacturers have actively sought alternative materials, producing low-nickel stainless steel fasteners.
