Calculate heat-treatment costs from the drawing callout.
Heat treatment is priced from the callout on the drawing, not guessed from the material. ARCNM reads the treatment — through-hardening, case hardening, induction hardening, nitriding, quench-and-temper, annealing, normalising and the rest of the ISO 4885 vocabulary, 38 kinds in all — extracts hardness and case depth per ISO 15787, and prices the step as a subcontract line with the order minimum a heat-treater charges. Heavier parts cost more to treat, the minimum amortises over the batch, and the lot-size curve shows where it stops dominating.
At a glance
- Inputs
- PDF drawing callout (kind, hardness, case depth per ISO 15787); part mass from the STEP model
- Machine classes
- priced as a subcontract line at your environment's heat-treatment rates, with the order minimum
- Standards applied
- ISO 4885 vocabulary (38 kinds) · ISO 15787 hardness and case depth · DIN 8580
- DfM checks
- hardness and case depth read from the drawing; machining after hardening priced as hard machining
- You get
- a subcontract line with its DIN 8580 code, placed in the routing after machining and before finishing and coating; the lot size at which the order minimum stops dominating
Which heat treatments are recognised and priced?
The full ISO 4885 register: the hardening family (through, surface, case, induction, flame, laser and electron-beam hardening), nitriding and nitrocarburising in their gas, plasma and salt-bath forms, thermochemical diffusion treatments (carburising, carbonitriding, boriding), quench-and-temper, austempering and martempering, the annealing family (normalising, soft annealing, spheroidising, stress-relief and bright annealing), solution treatment and ageing, sub-zero treatment and hydrogen-embrittlement relief. Each kind carries its ISO and German designation so the routing sheet names the step the way the standard does.
What drives the heat-treatment price?
The mass of the part first — heavier parts cost more to treat — then the treatment kind, and the order minimum, which dominates a small batch and fades with the lot. Your own heat-treater's price list replaces ARCNM's rates per environment, effective-dated, so a repeated calculation is reproducible.
What the calculation gives you
- A subcontract line per treatment with rate, mass and order minimum visible.
- The treatment as an ordered step on the routing — after all machining, before surface finishing and coating — exportable with its DIN 8580 code.
- The lot-size break-even where the order minimum stops dominating the unit price.
- The machining of the hardened part priced for the hardened material.
The treatment families and what they change
| Family (ISO 4885) | Examples | What changes | Follow-on step the routing expects |
|---|---|---|---|
| Through and surface hardening | quench-and-temper, induction, flame, laser | core or surface hardness, distortion | grinding of fits after hardening |
| Case hardening / diffusion | carburising, carbonitriding, boriding | hard case, tough core, case depth per drawing | grinding; threads usually masked |
| Nitriding | gas, plasma, salt-bath nitrocarburising | hard surface at low distortion | usually none — finish before nitriding |
| Annealing | normalising, soft, spheroidising, stress-relief | machinability, residual stress | none |
| Precipitation | solution treatment and ageing | strength of aluminium, stainless, nickel alloys | machining between solution and ageing |

Frequently asked questions
How much does heat treatment cost per part?
It depends on the part's mass, the treatment kind and the heat-treater's order minimum spread over the batch. ARCNM reads the treatment from the drawing and shows the treatment cost and the minimum's share separately, so a small batch of case-hardened parts is visibly minimum-driven.
Can I use my own heat-treater's prices?
Yes. Subcontract rates per treatment kind are environment settings, validated on entry and effective-dated. They apply to every calculation in that environment.
