FAQ

What work fits NAICS 331513?
  • Produce steel or iron replacement castings from existing patterns or reverse-engineered patterns, delivering finished castings machined to drawing tolerances and accompanied by dimensional inspection reports.
  • Short-run production of pump housings, valve bodies, and gearbox housings in ferrous alloys with accompanying metallurgical test reports and heat-treatment records.
  • Supply castings with specified post-cast heat treatment and surface preparation, including hardness testing, microstructure documentation, and certified material certificates.
  • Coremaking and molding services with pattern maintenance, sand handling records, and delivery of finished castings prepared for installation on fielded equipment.
When is NAICS 331513 a weak fit?
  • Investment casting and precision nonferrous casting: jobs producing small, precision stainless or nonferrous components, because those processes and alloys fall outside ferrous foundry casting scope.
  • Die casting and high-pressure nonferrous casting: production that uses metal-injection or die-casting for aluminum or zinc, because those are nonferrous manufacturing methods not covered here.
  • Metal fabrication and welding shops: contractors that cut, fabricate, or weld finished steel structures without performing molding, melting, or casting processes.
What solicitation language points to NAICS 331513?
  • Specification language requiring 'steel' or 'iron' castings with chemical analysis, heat-treatment certificates, and material traceability.
  • Deliverables calling for pattern drawings, first-article castings, dimensional inspection reports, and certified test results with part numbers.
  • Process requirements for molding, coremaking, sand reclamation, pour records, and metallurgical inspection such as hardness or microstructure documentation.
