Gray and Ductile Iron Castings for Engineering Applications
OK Foundry makes production castings in gray and ductile iron for almost every conceivable general industrial purpose and some special industrial segments like chemical process, petrochemical, and primary metals. Orders are filled for monthly releases of moderate volume castings as well as project quantities and spare or obsolete casting requirements. Although larger volumes of castings are possible with dedicated continuous production, OK Foundry maintains shorter lead times by running with smaller batch sizes and frequent setups for lean production of castings.
OK Foundry typically supplies the following grades of cast iron:
- ASTM A48, Standard Specification for Gray Iron Castings, Class 20, 25, 30, 35, and 40
- ASTM A536, Standard Specification for Ductile Iron Castings, Grades 60-40-18, 65-45-12, and 80-55-06
Other metal grades available on request.
OK Foundry makes prototype castings using traditional foundry pattern making techniques or advanced 3D digital technology. Click through the link below to learn more about which methods fit your project best.
