Stainless Steel 317L Duplex Stainless Steel Fasteners Hex Head Bolt M6-M64 DIN 960
1.317L 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.
What are the characteristics of 317L Stainless?
· Improved general and localized corrosion to 316L stainless
· Good formability
· Good weldability
2. Fasteners Specification:
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.
