What this NAICS covers

NAICS 332811 covers heat treating metal parts using controlled processes such as annealing, quenching, tempering, carburizing, and nitriding in furnaces and controlled-atmosphere equipment to change hardness, toughness, or microstructure without engaging in primary metal shaping.

Federal opportunities under 332811 typically involve contract heat treatment of vendor-supplied components to specified hardness and microstructural acceptance criteria, production run cycle records, metallurgical test reports, lot traceability, and adherence to specified furnace atmosphere controls and quench media.

FAQ

What work fits NAICS 332811?
  • Batch annealing of steel gears and shafts to specified Rockwell hardness and grain-size criteria with delivery of hardness charts.
  • Carburizing and tempering of components to required case depth and core hardness with metallurgical reports and case-depth measurements.
  • Vacuum heat treating of stainless steel parts to control oxidation and provide recorded cycle charts and post-process hardness tests.
  • Stress-relieving and normalizing welded assemblies to specified temperature profiles and documenting thermal cycle data for each lot.
When is NAICS 332811 a weak fit?
  • Primary metal fabrication or forging: supplier performs forming, forging, or major machining as the primary operation rather than standalone heat-treat processing.
  • Plating, coating, or thermal spray services: applies surface coatings or platings rather than altering bulk metallurgical properties through heat treatment.
  • Integrated OEM production lines where heat treating is incidental to assembly and the contract is for finished assemblies rather than discrete heat-treating services.
What solicitation language points to NAICS 332811?
  • Specifications list required hardness ranges, case depth, and acceptance tests such as Rockwell or microhardness traverses with pass/fail criteria.
  • Contract requires delivery of heat-treat cycle charts, furnace thermocouple data logs, and lot-based metallurgical laboratory reports.
  • Scope references required atmosphere controls (vacuum, controlled gas), specified quench media, or industry heat-treatment standards and process control documentation.
