Stainless Steel Castings

Who pours castings in this alloy, and can they hold my geometry and pour weight?

What it is

Parts produced by pouring molten metal into a mold. For reactive metals this requires vacuum or inert atmosphere melting and specialized mold systems, which is why the qualified supplier list is short.

Typical dimensions
Grams to several hundred pounds; envelope limited by furnace and mold capacity.
Also known as
cast parts, investment castings, precision castings, cast components

Suppliers

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

  • Milwaukee, WI · Converter
    10 lb to 4,000 lb

    Stainless and high alloy sand castings from 10 to 4,000 lb. Badger publishes its moulding method, which most foundries do not: airset NO-BAKE, giving closer dimensional tolerance and a cleaner surface than green sand at higher cost per mould. Casting weight range 10 to 4,000 lb. No AS9100, NADCAP or military specification qualification is claimed. Defense is one of several markets served.

Production methods

The same form, purchased as tolling on your own material.

Investment Casting 3

Building a ceramic shell around a wax pattern, melting the wax out and pouring metal into the resulting cavity. For reactive metals the pour is done under vacuum or inert atmosphere against specially formulated shells.

Sand Casting 2

Pouring metal into a mold formed in bonded sand. The lowest tooling cost route to a casting and the only practical one for very large parts, at the cost of surface finish and dimensional tolerance.

  • Milwaukee, WI · Converter
    10 lb to 4,000 lb

    Airset no-bake sand casting of stainless steels and high alloys. Badger publishes its moulding method, which most foundries do not: airset NO-BAKE, giving closer dimensional tolerance and a cleaner surface than green sand at higher cost per mould. Casting weight range 10 to 4,000 lb. No AS9100, NADCAP or military specification qualification is claimed. Defense is one of several markets served.
