Nickel Alloy Grade Data Sheet

Inconel 617

Inconel 617 is a solid-solution-strengthened nickel-chromium-cobalt-molybdenum alloy developed for high-temperature strength, oxidation resistance and metallurgical stability. The combination of nickel, chromium, cobalt and molybdenum provides useful creep and stress-rupture properties together with resistance to carburizing and oxidizing atmospheres. Alloy 617 is commonly supplied for gas turbines, industrial furnaces, heat-treatment equipment, petrochemical processing, power-generation systems and other high-temperature fabricated components.

Material Selection Guide

When to consider Inconel 617

This guide helps buyers connect service conditions with the typical advantage of Alloy 625. Final selection should consider medium concentration, temperature, pressure, fabrication, availability and budget.

Service Requirement Why Alloy 617 Helps Common Product Form Buyer Note
High-temperature load-bearing components Solid-solution strengthening provides useful creep and stress-rupture strength at elevated temperatures. Plate, bar, forgings, tube and fabricated assemblies Specify operating temperature, design life, stress level and thermal cycles.
Oxidizing furnace atmospheres Chromium and aluminum support formation of a protective oxide scale. Sheet, plate, tube, wire and furnace hardware Confirm maximum temperature, atmosphere composition and thermal cycling.
Carburizing environments The high nickel and chromium contents provide useful resistance to carburization. Furnace tubes, trays, baskets, fixtures and sheet Specify carbon activity, temperature and expected exposure time.
Gas-turbine and combustion systems Alloy 617 combines oxidation resistance, thermal stability and elevated-temperature strength. Sheet, plate, bar, tube, forgings and fasteners Confirm fatigue, creep, inspection and surface-finish requirements.
Petrochemical processing equipment The alloy resists many hot process environments while maintaining fabrication capability. Pipe, tube, fittings, plate and welded assemblies Review the complete process chemistry, pressure and operating temperature.
Complex welded fabrication Alloy 617 has good weldability when suitable procedures and matching filler metals are used. Plate, sheet, pipe, tube and welding wire Control cleanliness, joint design, heat input and post-weld inspection.

FAQ

Inconel 617 questions from buyers

Find practical answers about procurement, standards, fabrication and industrial applications.

Inconel 617 is used for gas turbines, combustion systems, industrial furnaces, petrochemical equipment, heat-treatment fixtures, power-generation systems and other components exposed to high temperatures and mechanical loading.

Yes. UNS N06617 is the standardized UNS designation for Inconel 617. The alloy may also be identified as Alloy 617, Nickel Alloy 617, W.Nr. 2.4663 or NiCr23Co12Mo.

No. Alloy 617 is primarily strengthened by solid-solution effects from cobalt and molybdenum. It is normally supplied in a solution-annealed condition rather than precipitation hardened like Inconel X-750 or Alloy 718.

YSN128 can quote plate, sheet, strip, round bar, rod, wire, seamless pipe, tube, forgings, rings, flanges, fittings, fasteners and welding wire. Cutting, forming, machining and drawing-based supply can also be discussed.

Common specifications include ASTM B168 for plate and sheet, ASTM B166 for rod and bar, ASTM B167 for seamless pipe and tube, ASTM B564 for forgings, ASTM B366 for fittings, AMS 5887 and AMS 5888. Related ASME specifications may be used for pressure equipment.

Yes. Alloy 617 has good weldability using gas-tungsten arc, gas-metal arc and other suitable nickel-alloy welding processes. Matching filler metals such as ERNiCrCoMo-1 may be specified, subject to the approved welding procedure and service requirements.

Yes. EN10204 3.1 material certificates can be supplied on request, including heat number, chemical composition, mechanical test results, heat-treatment information and inspection records. Additional PMI, ultrasonic or corrosion testing can be arranged when specified.

Please send the product form, dimensions, quantity, applicable ASTM, ASME or AMS standard, delivery condition, inspection requirements, destination and service temperature. Drawings should be included for forgings, fittings and custom-fabricated components.
