ASTM B637 UNS N07718 Forging Nickel Alloy Forging with High Strength

ASTM B637 UNS N07718 Forging Nickel Alloy Forging with High Strength

The UNS N07718 nickel-based alloy forgings certified by ASTM B637, with its core competitiveness ranging from ultra-low temperature toughness at -196°C to creep strength at 800°C (1275MPa), provide protection for aircraft engine disc shafts/nuclear power main valves/deep-sea equipment.

Inconel 718 core performance

High temperature strength: still maintain high strength at 650-800℃, tensile strength of 965-1275 MPa, yield strength of 550-1035 MPa, strength at 700℃ is 80% of room temperature

Corrosion resistance: oxidation resistance (1000℃), acid and alkali corrosion resistance and stress corrosion cracking resistance, especially in harsh environments containing Cl⁻, H₂S, etc.

Processing performance: can achieve the best mechanical properties through solid solution + aging heat treatment (such as 924-1010℃ solid solution, 718±14℃ aging), good weldability

Low temperature stability: still maintain chemical stability at -253℃, suitable for deep cold engineering.

Industry Standards: ASTM B637

1. ASTM B637 is an internationally accepted nickel-based alloy material standard that specifically regulates the medium- and high-temperature application requirements of precipitation-hardened nickel alloy bars, forgings, and forging billets, covering the manufacturing of core components in the fields of aerospace, energy equipment, and chemical equipment.
2. Material: Represented by Inconel 718 (UNS N07718/GH4169), others include Inconel X-750 (UNS N07750) and other similar alloys
3. Process: It covers two process paths: hot working (hot rolling, forging) and cold working (cold rolling, cold forging), requiring the material to have both high strength and processing adaptability.
