FAQ

What work fits NAICS 331512?
  • Producing precision stainless or carbon steel investment castings to print with associated material certifications and heat-treatment records.
  • Delivering small-to-medium series production runs of complex geometry steel castings with nondestructive testing such as radiography, ultrasonic testing, and magnetic particle inspection per specification.
  • Providing prototype investment castings with wax tooling development, first article inspection, metallurgical analysis, and sample approval cycles.
  • Supplying finish-machined steel castings delivered with dimensional inspection reports, lot traceability, and post-cast heat treatment documentation for critical component procurement.
When is NAICS 331512 a weak fit?
  • Sand casting of steel or other metals where the primary process uses sand molds rather than the wax pattern and ceramic shell workflow central to investment casting.
  • Non-steel metal casting where the contract specifies aluminum, bronze, or nickel alloy castings and steel investment casting processes and material controls are not required.
  • Machine shop or job shop work where the supplier purchases castings and performs only machining and assembly without performing investment casting processes or providing casting source documentation.
What solicitation language points to NAICS 331512?
  • Statement of work requires wax tooling approval, ceramic shell processing steps, de-wax records, and shell removal documentation as contract tasks.
  • Evaluation criteria list required NDT reports by lot such as radiographic film, ultrasonic reports, or magnetic particle inspection tied to casting acceptance.
  • Contract performance standards demand melt and pour records, heat-treatment charts, certified material test reports (CMTRs), and dimensional inspection reports for each casting lot.
