Metal Heat Treating

NAICS 332811 · Fabricated Metal Product Manufacturing · SBA size standard: 750 employees

Metal heat treaters receive customer parts or raw stock, run them through furnaces under tightly controlled time-temperature-atmosphere cycles, then perform hardness and metallurgical checks before return. For a shop that runs batches of alloy steel components with specific hardness targets, the specialists turn incoming job tickets into furnace schedules, track each load through multiple furnace runs and quench steps, maintain pyrometry and atmosphere logs, and generate the paperwork the customer expects on delivery. Metallurgical decisions and final sign-off stay with the heat-treat supervisor.

What makes this business different

  • Customer parts arrive with strict metallurgical specifications, required hardness ranges, and exact process instructions that cannot be altered without written approval
  • Multiple furnace types (vacuum, atmosphere, salt bath, tempering ovens) with limited capacity and long cycle times
  • Pyrometry, thermocouple calibration, and atmosphere control records that must be kept for years
  • Quench media management, safety data sheets, and spill containment requirements
  • Batch traceability from incoming material through every furnace run to final shipment
  • Furnace qualification runs, survey reports, and preventive maintenance tied to production
  • Repeat industrial customers who send the same part numbers on regular schedules with certified test results

Workflows

Job intake and specification review

Starts when: A customer sends parts with a purchase order or job ticket

  1. Capture part number, material, quantity, required hardness range, and any special instructions from the accompanying documents
  2. Verify specifications against the shop's approved process sheets for that material and hardness target
  3. Assign a unique batch identifier for full traceability through every subsequent step
  4. Check furnace availability and type against the required cycle parameters
  5. Draft the internal work order with exact parameters and send for review

Watch for: Metallurgical requirements must be captured exactly as written on customer documents; Any deviation from the specified process requires written customer authorization before processing

Furnace scheduling and load planning

Starts when: After job intake and at the start of each shift

  1. Group pending jobs by furnace type, temperature range, atmosphere requirements, and cycle duration
  2. Build a daily or shift furnace schedule that respects heat-up rates, cooldown constraints, and total load limits
  3. Calculate load weights, fixture or basket requirements, and fixture spacing for each run
  4. Reserve dedicated time windows for required temperature uniformity surveys or qualification runs
  5. Flag any jobs needing special quench media, atmosphere, or separation from incompatible alloys

Watch for: Furnace capacity is limited by both physical size and total heat input; Certain alloys cannot share a furnace run due to contamination or cross-contamination risk

Process execution and monitoring

Starts when: When a furnace is ready for the next scheduled load

  1. Load parts into the specified fixtures or baskets exactly as called out on the work order
  2. Set and independently verify all temperature setpoints, soak times, atmosphere controls, and quench parameters
  3. Monitor and log each segment of the cycle in real time using furnace instrumentation
  4. Record any deviations from the planned parameters and notify the supervisor immediately
  5. Unload the batch at the correct time and transfer to the next operation such as tempering or cooling

Watch for: Quench timing must be precise to achieve the required microstructure; All critical process variables must be recorded automatically or by the operator at the furnace

Hardness inspection and testing

Starts when: After each heat treat cycle and any required tempering is complete

  1. Select sample parts from the batch per the sampling plan and perform the specified hardness tests
  2. Record all readings and compare them directly against the customer's hardness range requirements
  3. Prepare metallurgical samples for microstructure examination when required by the specification
  4. Generate a test report that includes the batch identifier, furnace run data, and all test results
  5. Flag any out-of-spec parts or batches for immediate supervisor review before further processing

Watch for: Test equipment must be calibrated on a defined schedule; Certain hardness ranges require specific test methods such as Rockwell or Vickers

Material, equipment and consumables tracking

Starts when: Daily, after each major run, and on a weekly basis

  1. Track the location and status of every customer-owned batch from receipt through processing and shipping
  2. Monitor inventory levels of quench oils, process gases, salts, fixtures, and replacement parts
  3. Schedule and document calibration events for thermocouples, instruments, and test equipment
  4. Log consumption of all furnace consumables and generate reorder recommendations
  5. Produce on-demand traceability reports linking each batch to its complete process history

Watch for: Customer-owned parts must remain segregated and traceable at all times; Certain quench media and gases have strict storage, handling, and disposal rules

Quality records and certification generation

Starts when: Upon completion of each batch and on scheduled quarterly dates

  1. Compile all furnace charts, digital logs, atmosphere records, pyrometry data, and hardness test results
  2. Draft certificates of conformance that list every process parameter used for that batch
  3. Organize and cross-reference pyrometry surveys, thermocouple calibrations, and instrument records
  4. Prepare the complete shipment paperwork packet including packing slips, test reports, and certifications
  5. Archive the full batch file in the required long-term storage system according to the retention schedule

Watch for: Many customers require specific formats for certification documents; Records must be available for audit on short notice

Equipment maintenance and compliance tracking

Starts when: On fixed calendar intervals, after each use, and after any repair

  1. Generate preventive maintenance checklists tailored to each furnace and instrument
  2. Track thermocouple usage hours, salt bath chemistry analysis, and quench media condition
  3. Schedule and document all required temperature uniformity surveys and system accuracy tests
  4. Maintain current safety data sheets, environmental compliance logs, and spill containment records
  5. Flag upcoming recertification or requalification dates for furnaces, controllers, and test equipment

Watch for: Pyrometry standards require specific test frequencies and procedures; Local environmental and safety regulations govern emissions, waste handling, and reporting
