Reading POs and Specs
A heat treat PO may reference AMS 2759/1 for steel parts, AMS 2770 for aluminum, a customer-specific specification, a hardness range, a case depth, a part-specific drawing note or a flow-down clause. A model can extract those requirements, identify the governing revision and list what the shop must record: temperature, soak time, quench medium, temper cycle, hardness testing frequency. The result is a requirements summary the contract reviewer confirms, instead of a blank page.
- Extract spec number, revision, class and any customer-specific overrides
- List required tests and sampling frequency
- Flag unusual requirements: witness testing, special packaging, restricted quenchants
- Link each requirement to the page and line it came from
Drafting Quotes From History
Heat treat pricing is commonly by weight, by load or by piece, with adjustments for cycle length, atmosphere, fixturing, hardness testing and cert. A model with access to past jobs can find loads of similar material and weight, show actual cycle times and fixture needs, and propose a draft price for the estimator to adjust. It is most useful for one-off RFQs where the estimator would otherwise search old orders by hand.
Cross-Checking Certs and Records
The model can compare a drafted certificate with the PO and the furnace record and flag differences: wrong revision, missing hardness result, cycle outside the specified range, or an instrument whose calibration status is past due. These are checks a careful quality person already does, so the benefit is consistency and speed, especially on a busy shipping day. The quality manager still signs.

Heat Treatment Furnace Load Worksheet
Build a furnace load sheet row by row: pieces, unit weight, section thickness and process, with total load weight and a planning soak time.
Answering Questions About Your Records
Aerospace and medical customers ask for historical evidence long after the job ran. A private assistant over furnace logs, travelers and certs can answer questions like 'show every load of this alloy in furnace 3 last quarter with hardness results' with citations to the record. That is a retrieval task, not a decision task, and it saves hours during audits and customer complaints.
Guardrails and Deployment
Keep the model read-only against your ERP and quality records, show sources for every extracted value, log what it did and require human approval before anything is written or sent. If customer drawings are ITAR or CUI, run the model on your own hardware inside your boundary rather than a public cloud service. Open-weight models served locally are adequate for extraction and drafting at this scale.
When It Is Not Worth It
If your work is mostly repeat parts on a few specs and your records are already clean, your estimators and quality staff are probably faster than any tool. Consider AI when RFQ variety is high, audit questions consume days, or errors in certs are costing you shipments.
Frequently asked questions
Can AI read heat treat specifications like AMS 2759?
A language model can read the text of a specification you provide and extract requirements, but it can misread tables or revisions. Use it as a first pass, require citations to the source page, and have a qualified person confirm the final requirement list. Do not rely on a model's memory of a specification.
Is AI allowed in a NADCAP accredited shop?
NADCAP audits your processes and records, not whether you use software, but any tool that influences records must be controlled and its outputs reviewed. Document how AI is used, keep humans accountable for signing and releasing, and check customer contract restrictions first.
How do heat treaters usually price work?
Common bases are per pound or kilogram, per load, per piece or per hour of furnace time, with minimum charges and add-ons for testing, fixturing, certification and rush service. The best basis is the one that matches what limits your furnaces for that kind of work.
