Suppliers

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

Mills and producers 5

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

    Long product bar and rod in stainless and specialty steel. MELT ORIGIN re-confirmed 2026-07-30 and corroborated rather than superseded: this is an integrated domestic producer that melts its own material.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.

    source
  • Carpenter Technology Corporation Verified
    Philadelphia, PA · Mill
    US melted

    Specialty long products including the precipitation hardening grades. Specialty stainless among the stated alloy families, alongside high temperature alloys, nickel-copper, titanium, soft magnetic alloys and powder materials.

  • Electralloy Verified
    Oil City, PA · Mill
    US melted

    Bar in austenitic, Nitronic, martensitic, precipitation hardening and duplex grades.

  • North American Stainless Reported
    Ghent, KY · Mill
    US melted

    Integrated melting through finishing at Ghent, Kentucky. MELT ORIGIN re-confirmed 2026-07-30 and corroborated rather than superseded: this is an integrated domestic producer that melts its own material.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.

  • Universal Stainless & Alloy Products Verified
    Bridgeville, PA · Mill
    US melted

    Unverified lead. No company source was reached; confirm product range before sourcing. Specialty bar, forging quality billet, ingot, plate, specialty shapes and coil, produced across Bridgeville and Titusville PA, North Jackson OH and Dunkirk NY. 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.
