TECHNICAL INFORMATION

Technical Specifications

Detailed technical information including chemical composition, mechanical properties, standards and available dimensions.

Chemical Composition

ASTM B637 fixes 50.0–55.0% nickel, 17.0–21.0% chromium, 4.75–5.50% niobium plus tantalum and 0.65–1.15% titanium for UNS N07718, and this rectangle bar is quoted to the same window. Therefore, niobium and titanium are the elements that age-harden this rectangle bar.

Consequently, the full composition table on the Inconel 718 material page lists every element against its ASTM B637 limit for this rectangle bar.

Mechanical Properties

The minimum room-temperature values below apply to UNS N07718 bar in the solution-treated and precipitation-hardened condition. Transverse and heavy-section requirements are lower per AMS 5662; the applicable standard governs final acceptance.

Condition Product Size Tensile Strength Yield Strength, 0.2% Offset Elongation Hardness
Solution Treated + Precipitation Hardened (AMS 5662 / AMS 5663) Up to 254 mm (10 in.) ≥185 ksi (1276 MPa) ≥150 ksi (1034 MPa) ≥12% ≥331 HB
  • The standard double age holds the rectangle bar near 718 °C (1325 °F) for 8 hours, furnace cools to 621 °C (1150 °F), and holds 18 hours total before air cooling.

Physical Properties

Published references record a density near 8.19 g/cm³ and a melting range of 1260–1336 °C for this rectangle bar. Moreover, design work on this rectangle bar starts from the aged condition rather than the annealed one.

In addition, the physical properties table on the Inconel 718 material page carries the modulus, the thermal expansion and the remaining design values behind this rectangle bar.

Heat Treatment

Precipitation hardening is what separates Inconel 718 rectangle bar from solid-solution alloys. We supply the rectangle bar in the condition below that your application needs.

Condition Typical Treatment
Solution Treated Held near 940–1010 °C (1725–1850 °F), then air cooled
Solution + Age Hardened Two-step age near 718 °C (1325 °F) and 621 °C (1150 °F) for full strength
Stress Relieved Available when specified for the application
Custom Condition Heat treatment according to the agreed specification

Standards

ASTM B637 is the principal UNS N07718 bar and rod document for this rectangle bar, issued by ASTM International. Moreover, ASME SB637 covers pressure equipment built from this rectangle bar and SAE AMS 5662 and 5663 cover aerospace procurement.

Standard Product or Application
ASTM B637 Nickel alloy bar, rod and forgings for high-temperature service
ASME SB637 ASME counterpart for pressure equipment
SAE AMS 5662 / 5663 Nickel alloy 718 bar, forgings and rings
