Stainless Steel 317 Bolts, UNS S31700 Bolts Supplier & Exporter

STAINLESS STEEL 317 BOLTS GENERAL PROPERTIES:

317L is a molybdenum bearing, low carbon content "L" grade austenitic stainless steel that provides improved corrosion resistance over 304L and 316L stainless steels. The low carbon provides resistance to sensitization during welding and other thermal processes. 317L is non-magnetic in the annealed condition but may become slightly magnetic as a result of welding.

STAINLESS STEEL 317 BOLTS APPLICATIONS:

• Flue-gas desulfurization systems
• Chemical process vessels
• Petrochemical
• Pulp and Paper
• Condensers in power generation

STAINLESS STEEL 317 BOLTS CORROSION PROPERTIES:

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.

STAINLESS STEEL 317 BOLTS WELDING:

317L is readily welded by a full range of conventional welding procedures (except oxyacetylene). AWS E317L/ER317L filler metal or austenitic, low carbon filler metals with molybdenum content higher than that of 317L, or a nickel-base filler metal with sufficient chromium and molybdenum content to exceed the corrosion resistance of 317L should be used to weld 317L steel.

STAINLESS STEEL 317 BOLTS CHARACTERISTICS:

• Improved general and localized corrosion to 316L stainless
• Good formability
• Good weldability

Harsh Steel produces duplex fasteners in all grades of duplex, to customer specification. Duplex grades are a mixed microstructure of Austenite and Ferrite, combining the properties of both (hence the name DUPLEX). Duplex stainless steels have high corrosion resistance as well as a high strength. Mechanical properties are around double that of a typical austenitic grade such as 316. They would also normally offer higher stress cracking resistance in Chloride solutions for example. They are composed typically of 22% Chromium, 5 % nickel. Having worked with duplex since its outset, the duplex bolting continues to account for a core part of our business, along with Super duplex.

We are proud that Harsh Steel is the world’s number one bespoke producer of Super Duplex bolting. Super Duplex stainless steel grades are similar to standard duplex, but they contain a higher content of Chromium, thus enhancing the corrosion resistance and mechanical properties. Harsh Steel produces fasteners in all three types of Super Duplex.

Harsh Steel’s substantial experience in working with high nickel alloys bolting is crucial as they are extremely difficult materials to machine and can require various forms of additional treatment to ensure full conformity. Related by their high percentage of nickel in their composition, these highly corrosion-resistant materials are widely used in the petrochemical and offshore sector, and are often better known by their registered trade names (e.g. Inconel®, Hastelloy®, Monel® and Nimonic®).
