Stainless Steel Ingot

Who melts this metal in the United States, and is the melt source DFARS compliant?

What it is

The first solid form after melting. A large cast cylinder, typically double or triple vacuum arc remelted for aerospace and defense use, that is subsequently broken down into billet, slab or bar.

Typical dimensions
Commonly 26 to 36 inches diameter, several thousand to 20,000+ lb per ingot.
Also known as
ingots, melt stock, VAR ingot, remelt ingot

Grouped by what they actually are. A mill and a distributor answer different needs.

  • New Castle, PA · Mill
    US melted

    Bottom-poured ingot from a 45 ton electric arc furnace with split secondary ASEA-SKF ladle refining and vacuum degassing. Electroslag and vacuum arc remelting are available where aerospace or power generation cleanliness is required. Ingot size and weight range are not published. Ask, because it sets the maximum forging you can source downstream. Stainless is melted at the Irvine plant on the vacuum oxygen decarburisation unit.

  • Bridgeville, PA · Mill
    US melted

    Forging quality billet and ingot. Melt routes offered span AOD, ESR and VAR at Bridgeville and VIM followed by ESR or VAR at North Jackson. These are different cleanliness levels rather than synonyms, and an aerospace specification usually names the one it requires, so confirm the route as well as the origin. Ingot size range is not published.
