Heat Treatment, Furnaces & Thermal Processing calculator

Stress Relief Cost Calculator

Estimate stress relief cost from treated parts or pounds, stress relief rate, capture percent, and fixed furnace or certification adders. Use it to make the cost driver visible before quoting, scheduling, purchasing, or approving the heat treat route.

What this calculator does

  • Estimate stress relief cost from treated parts or pounds, stress relief rate, capture percent, and fixed furnace or certification adders.
  • Use it when weldments, machined parts, castings, forgings, or additive parts need stress relieving before finish operations.
  • Estimates job cost for stress relieving based on treated quantity and fixed lot adders.

Formula used

  • Captured stress relief cost = stress relieved quantity × stress relief cost rate × stress relief cost capture
  • Total stress relief cost = captured stress relief cost + fixed stress relief adder

Inputs explained

  • Stress relieved quantity: Use the count, pounds, hours, gallons, or batches covered by the estimate.
  • Stress relief cost rate: Use the current heat treat rate, energy rate, material cost, labor rate, or supplier quote basis.
  • Stress relief cost capture: Enter the portion of the cost or workload that should be included in this scenario.
  • Fixed stress relief adder: Add setup, certification, fixture, minimum charge, freight, validation, or containment cost not captured per unit.

How to use the result

  • Use it for fabrication, machining, casting, forging, or additive manufacturing route cost reviews.
  • It does not verify residual stress reduction, distortion, or metallurgical suitability. Use approved process specifications for release.

Common questions

  • What is the stress relief cost calculator for? It estimates the cost of a stress relief thermal cycle for a lot or batch.
  • What numbers should I enter? Use treated pounds or parts, the cost rate, capture percent, and any fixed furnace, certification, or minimum-charge adder.
  • How should I use the result? Use the result to decide whether stress relief cost is material to the quote or route comparison.
  • When is this only an estimate? It is only an estimate when fixture weight, furnace minimums, or inspection requirements are not included.
