Inconel 625 Scrap/ Inconel 625 Foundry Scrap/ Inco 625 Scrap

Product Description

Inconel 625 (UNS N06625) is a non-magnetic, solid-solution strengthened nickel-chromium-molybdenum-niobium superalloy. It is characterized by outstanding resistance to pitting, crevice corrosion, and high-temperature oxidation, alongside high tensile and creep strength from cryogenic temperatures up to 982°C (1800°F).

Chemical Composition Data (wt %)

No chemical symbols included; values represent standard nominal weight percentages according to ASTM B443/B446:

Mechanical & Physical Properties (Annealed Condition)

• Density: 8.44 grams per cubic centimeter

• Melting Range: 1290 to 1350 degrees Celsius

• Ultimate Tensile Strength: 830 to 1000 Megapascals

• Yield Strength (0.2% Offset): 415 to 600 Megapascals

• Elongation at Break: 30 to 60 percent

• Hardness: 85 to 95 Rockwell B (typical)

• Maximum Service Temperature: 982 degrees Celsius

Scrap Classification & Re-Melting Guidelines

• Scrap Grade Classification: Vacuum Induction Melting (VIM) / Electric Arc Furnace (EAF) feed grade solids and processed turnings.

• Foundry Forms: Heavy plate cutoffs, pipe sections, forged rings, valve castings, pump impellers, wire cutoffs, and clean solids/chips.

• Quality Requirements: Must be sorted away from tungsten-containing or high-iron nickel grades. Free of oil, grease, scale, paint, lead/zinc solder contaminations, and free-machining sulfur compounds to ensure optimal melt recovery.
