Inconel 925 Scrap/ Inconel 925 Foundry Scrap/ Inco 925 Scrap

Product Description

Inconel 925 (UNS N09925 / Incoloy 925) is an age-hardenable nickel-iron-chromium superalloy engineered to combine high mechanical strength and outstanding corrosion resistance. The addition of molybdenum, copper, titanium, and aluminum provides exceptional resistance to sulfide stress cracking and stress-corrosion cracking in sour (hydrogen sulfide-containing) crude oil and natural gas production environments.

Chemical Composition Data (wt %)

No chemical symbols included; values represent standard nominal weight percentages according to ASTM B805:

Mechanical & Physical Properties (Aged Condition)

• Density: 8.08 grams per cubic centimeter

• Melting Range: 1311 to 1366 degrees Celsius

• Ultimate Tensile Strength: 1130 to 1240 Megapascals

• Yield Strength (0.2% Offset): 760 to 900 Megapascals

• Elongation at Break: 18 to 25 percent

• Hardness: 32 to 38 Rockwell C

• Maximum Service Temperature: 540 degrees Celsius

Scrap Classification & Re-Melting Guidelines

• Scrap Grade Classification: Premium Vacuum Induction Melting (VIM) / Vacuum Arc Remelting (VAR) quality low-carbon alloy scrap.

• Foundry Forms: Wellheads, downhole tubular scrap, valve bodies, forged shaft cutoffs, heavy plate ends, and clean processed turnings/borings.

• Quality Requirements: Must be strictly isolated from high-copper brasses or bronzes, free-machining high-sulfur alloys, and non-nickel stainless steels. Scrap must be fully cleaned of heavy grease, oil, scale, and non-metallic coatings prior to vacuum or induction remelting to maintain precise titanium and aluminum precipitation ratios.
