Stainless Steel Billet

I need forging stock. Who supplies billet in this alloy and diameter?

What it is

Ingot that has been forged or rolled to a smaller round or square cross section, refining grain structure and homogenizing the microstructure. The standard input stock for forging and extrusion.

Typical dimensions
Commonly 4 to 16 inches diameter for aerospace alloys.
Also known as
billets, forging stock, forge stock, bloom

Suppliers

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

Companies that manufacture this form. Mill direct means longer lead times and mill minimums, with full melt traceability.

  • ATI Inc. Verified
    Dallas, TX · Mill Converter
    US melted

    Billet for onward forging and rolling. MELT ORIGIN re-confirmed 2026-07-30 and corroborated rather than superseded: this is an integrated domestic producer that melts its own material. It remains a per-heat question regardless. DFARS 252.225-7009 status is settled on the mill certificate for the specific heat, not by the company record.

  • Bridgeville, PA · Mill
    US melted

    Unverified lead. No company source was reached; confirm product range before sourcing. Forging quality billet. Re-confirmed 2026-07-30 and corroborated by the melt routes established this pass: AOD, ESR and VAR at Bridgeville and VIM plus ESR or VAR at North Jackson. Those are different cleanliness levels, not synonyms. An aerospace specification usually names the one it requires, so ask for the route as well as the origin.
