Stainless Steel 317L Duplex Stainless Steel Fasteners Hex Head Bolt M1.6-M39 DIN 931

1. Fasteners Specification:

2.317L description

317L has excellent corrosion resistance in a wide range of chemicals, especially in acidic chloride

environments such as those encountered in pulp and paper mills. Increased levels of chromium,

nickel and molybdenum compared to 316L stainless steel improve resistance to chloride pitting

and general corrosion. Resistance increases with molybdenum alloy content. 317L is resistant to

sulfuric acid concentrations up to 5 percent at temperatures as high as 120°F (49°C). At

temperatures under 100°F (38°C) this alloy has excellent resistance to solutions of higher

concentration. However, service tests are recommended to account for the affects of specific

operating conditions that may affect corrosion behavior. In processes where condensation of

sulfur-bearing gases occurs, 317L is much more resistant to attack at the point of condensation

than conventional alloy 316. The acid concentration has a marked influence on the rate of attack

in such environments and should be carefully determined by service tests.

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.
