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.

Badger Alloys, Inc. Reported10 lb to 4,000 lb
Steel sand castings from 10 to 4,000 lb, from an integrated pattern shop, foundry and machine shop. 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.

Harrison Steel Castings Company Reported
Carbon and low to medium alloy steel castings, with military among the industries served. The moulding method is not published, so this is recorded as a casting product rather than a named casting process. The company site returned 403, so this rests on directory and trade listings.

Near-net investment castings in plain carbon and low alloy steel.

Production methods
The same form, purchased as tolling on your own material.
Investment Casting 1
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.
-
Investment casting of plain carbon and low alloy steels, plus rapid prototype casting. Two Wisconsin plants. No casting size or weight range is published and no defense qualification is claimed. Check before treating this as a qualified source.

Sand Casting 1
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.

Badger Alloys, Inc. Reported10 lb to 4,000 lb
Airset no-bake sand casting of carbon and alloy steels. 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.
