Monel 400 Scrap, Monel 400 Foundry Scrap, Alloy 400 Scrap

Product Description

Monel 400 (UNS N04400 / W.Nr. 2.4360) is a solid-solution binary nickel-copper alloy strengthened exclusively by cold working. It exhibits high strength and toughness over a wide temperature range, along with exceptional resistance to sea water, hydrofluoric acid, sulfuric acid, and alkalis.

Scrap Classification & Re-Melting Guidelines

• Scrap Grade Classification: Primary nickel-copper solid scrap for direct charge in air induction melting (AIM) or electric arc melting.

• Foundry Forms: Heavy plate cutoffs, valve bodies, pump shafts, heat exchanger tubing, marine fittings, and clean processed turnings.

• Quality Requirements: Must be kept strictly separate from iron-base stainless steels, chrome-bearing nickel alloys, and free-machining grades containing sulfur or lead. Free from excessive oxidation, grease, oil, and non-ferrous solder contamination.
