Sourcing Heat Treatment in Turkey
What an industrial buyer needs to know before requesting quotations for heat treatment from Turkey-based suppliers.
Overview
Sourcing heat treatment from Turkey is one of the recurring decisions of any industrial buyer who needs to balance unit cost, quality control and lead time. This page collects what an EU buyer should know before opening a Request for Quotation for heat treatment suppliers in Turkey: typical materials, tolerances expected on the drawing, certifications worth asking for, current price positioning and shipping turnaround.
From a pure cost angle, Turkey prices heat treatment roughly 20–35% lower compared to the average European baseline. Real numbers depend on volume, alloy and surface treatment, but this gap is what justifies a sourcing exercise toward Turkey in the first place. Cost is rarely the only variable: lead time, audit access, certifications and supplier capacity at the right volume usually decide which suppliers actually make the shortlist.
A typical first article from a Turkey-based heat treatment shop takes 7–21 working days, plus 3–7 shipping days of shipping to central Europe. Series production lead time depends on volume and capacity reservation: most established shops want a forecast horizon of 60 to 90 days to plan raw materials and surface treatment subcontractors.
When to choose this process
Always cite hardness HRC/HRB and depth requirements explicitly in the drawing.
Heat treatment changes the metallurgical structure of metals to reach target hardness, toughness or fatigue life. Process choice depends on alloy: through-hardening for 42CrMo4, case-hardening for 18NiCrMo5, vacuum for high-precision parts.
Why source here — Turkey
- Hourly labour cost 50–70% below EU average
- Customs union with EU (no import duties on most industrial goods)
- 3–7 day road shipping to central Europe
- Mature steel and forging base, dozens of EN 1090 shops
What to watch out for
- Currency volatility (TRY) — fix prices in EUR/USD
- Quality dispersion: select certified shops, audit before first PO
Typical materials
- Carbon and alloy steels
- Stainless
- Aluminium (T6, T7)
- Cast iron
- Titanium (annealing)
Typical tolerances
Hardness ±2 HRC; case depth ±0.1 mm; allow distortion budget on long parts.
Certifications to ask for
- CQI-9 (auto)
- NADCAP HT (aero)
- AMS 2750 pyrometry
- ISO 9001
- IATF 16949
- EN 1090
- PED 2014/68/EU
Frequently asked questions
Is it worth sourcing heat treatment from Turkey?
It pays off when the lower hourly rate (20–35% lower) beats the logistic friction (3–7 shipping days) and the selected supplier holds the required certifications (ISO 9001, IATF 16949). Below ~200 pcs/year it often doesn't; above ~1,000 pcs/year the math almost always tips in favour.
Will heat treatment distort my part?
Yes, slightly. Plan a finish grind/turn after treatment on critical bearing surfaces, and use jigs/fixtures for long thin parts.
Turkey or Eastern Europe — which one?
Turkey wins on heavy steel, large forgings and price; Poland/Czech win on machined precision parts and proximity to Germany.
