Inconel 718 Scrap/ Inconel 718 Foundry Scrap/ Inco 718 Scrap

Product Description

Inconel 718 (UNS N07718 / W.Nr. 2.4668) is a precipitation-hardenable nickel-chromium-iron superalloy featuring high yield, tensile, and creep-rupture strength up to 704°C (1300°F). It displays outstanding weldability and resistance to post-weld strain-age cracking, making it the premier alloy for aerospace gas turbines, rocket engines, and oil and gas components.

Chemical Composition Data (wt %)

No chemical symbols included; values represent standard nominal weight percentages according to ASTM B637:

Mechanical & Physical Properties (Precipitation-Hardened Condition)

• Density: 8.19 grams per cubic centimeter

Scrap Classification & Re-Melting Guidelines

• Scrap Grade Classification: Premium Vacuum Induction Melting (VIM) / Vacuum Arc Remelting (VAR) quality superalloy charge material.

• Foundry Forms: Forged ring ends, turbine disc cutoffs, fasteners, structural sheet scrap, heavy turnings, and clean solids.

• Quality Requirements: Must be strictly isolated from high-cobalt or non-niobium nickel alloys to preserve the exact niobium-to-titanium ratio required for gamma-double-prime phase hardening. Must be free of coatings, oils, dirt, scale, and non-metallic contamination before remelting.
