What is the selection principle of stainless steel wire for fasteners?

Core Tip: Fasteners are the basic parts of hardware machinery. The demand is very large. In certain occasions, the fastener materials need to meet the conditions of severe corrosion or high strength. Many stainless steel and ultra-high-strength stainless steels have emerged, so tighten. How to choose stainless steel wire?

Fasteners are hardware mechanical basic parts, which are in great demand. Usually bolts, screws, rivets, etc. are used to ensure safety or generally do not consider the adverse effects of temperature or other dangerous conditions. Commonly used materials are carbon steel, low alloy steel and non-ferrous metals. However, in certain occasions, fastener materials need to meet severe corrosion or high strength conditions, and many stainless steel and ultra-high strength stainless steels have emerged.

The selection of excellent stainless steel for fastener production is mainly considered from the following five aspects:

1. Requirements for mechanical properties, especially strength, of fastener materials.
2. Requirements for the corrosion resistance of the material under working conditions.
3, the working temperature on the material's heat resistance (high temperature strength, oxidation resistance) requirements.
4. Requirements for material processing performance in terms of production process.
5, other aspects, such as weight, price, procurement factors must be considered.
