UNS S32205 Duplex 2205 Duplex Stainless Steel Fasteners Hex Bolt M1.6-M39 DIN931
1. Fasteners Specification:
2.Duplex 2205 description
Duplex 2205 stainless steel (both ferritic and austenitic) is used extensively in applications that require good corrosion resistance and strength. The S31803 grade stainless steel has undergone a number of modifications resulting in UNS S32205, and was endorsed in the year 1996. This grade offers higher resistance to corrosion.
At temperatures above 300°C, the brittle micro-constituents of this grade undergo precipitation, and at temperatures below -50°C the micro-constituents undergo ductile-to-brittle transition; hence this grade of stainless steel is not suitable for use at these temperatures.
3.Fasteners package method
Often small hardware, fasteners and other parts are packaged in bags and displayed in bins or on
hangers. Bagging is the most effective way to package and organize small parts, while also being the
most flexible and affordable. In order to better protect the products during transportation, we will pack the
packed products in wooden cases.
4.Fasteners Application
A fastener (US English) or fastening (UK English) is a hardware device that mechanically joins or affixes
two or more objects together. In general, fasteners are used to create non-permanent joints; that is, joints
that can be removed or dismantled without damaging the joining components. Welding is an example of
creating permanent joints. Steel fasteners are usually made of stainless steel, carbon steel, or alloy steel.
