Heat Treatment – Certified Precision for Highly Stressed Components
Heat-treated workpieces determine whether a machine will run reliably for decades or fail prematurely. Ammann Components combines Swiss quality standards with state-of-the-art equipment and offers hardening, tempering, and annealing in large-scale production. Every component is fully traceable and inspected according to ISO 9001 – from the first induction coil to the final report.

Why Modern Heat Treatment is Essential
Components in mechanical and automotive engineering are exposed to higher mechanical, thermal, and corrosive loads than ever before. Without targeted heat treatment, they lack structural strength, toughness, and dimensional stability. By continuously optimizing parameters – furnace atmosphere, holding time, quenching medium – we meet even the strictest OEM specifications and extend the service life of complex components.
As a system supplier, we take responsibility for the entire process chain: from raw part to wear-resistant finished product, we document every step in real time. This reduces downtime costs and ensures reliable planning for your production and series launches.
Processes at a Glance – Hardening, Tempering, Annealing
Each application requires specific demands on surface hardness, toughness, or distortion. We use several furnace types and integrate them seamlessly into upstream casting and downstream coating lines. This creates continuous process chains: raw parts move directly from the melting furnace into the hardening tower, through controlled quenching baths, and on to final machining – all under one roof. A central batch control ensures that temperature profiles, atmospheres, and holding times are precisely matched to material and geometry.
- Direct hardening: pinpoint surface hardening by induction for shafts, pins, and gears
- Tempering: austenitizing, quenching, tempering – achieves high yield strength with good toughness
- Soft annealing & normalizing: creates machinable structures before CNC processing
- Stress-relief annealing: reduces residual stresses after welding or casting
Your Benefits at a Glance
- Consistent series quality: automated furnace monitoring with SPC trend analysis
- Short lead times: combined hardening lines located directly next to CNC machining
- Certified processes: ISO certificate package and EN 1090 EXC3 compliance
- Cost transparency: fixed price per batch, inspection reports included
This combination of process automation, certification, and cost clarity results in fewer complaints, shorter supply chains, and predictable margins – strengthening your competitiveness and allowing you to focus on innovation instead of rework.
Quality Assurance & Certifications
Zero-defect tolerance governs every stage – from batch entry to the digital inspection report:
- ISO 9001 – Quality management since 2001
- ISO 14001 – Environmental management, annual energy reporting
- ISO 45001 – Occupational safety, zero reportable accidents in 2024
- EN 15085-2 CL1 – Welding certification for safety-critical assemblies
- EN 1090-2 EXC3 – Structural standard for highly stressed components
All test cycles are validated with thermocouples, CT-scanned, and ISO-certified. Ammann Components is committed to transparent processes, responsible resource use, and continuous improvement – verifiable for customers, audits, and partners.

FAQ – Frequently Asked Questions on Heat Treatment
What is the minimum quantity for series orders?
For series orders, we typically recommend an annual demand of around 1,000 pieces, as fixtures and testing processes become economically viable. Smaller pilot batches for process validation are of course possible and scalable.
Which materials can Ammann Components harden?
We harden alloyed, unalloyed, and stainless steels, gray cast iron, ductile iron, and selected aluminum alloys. A material datasheet is sufficient to define the optimal cycle and guarantee microstructure, surface hardness, and dimensional stability.
How quickly will I receive inspection reports?
Hardness curves, temperature profiles, and atmosphere data are digitally signed for each batch. Shortly after release, you will receive a download link where all reports remain securely available for ten years – ideal for internal or customer audits.
Can Ammann also machine tempered parts?
Yes, our CNC centers process hardened surfaces up to 62 HRC. High-performance carbide tools and internal cooling ensure constant tool life, while 3D measuring technology checks every fit inline and delivers ready-to-install parts with documentation.
How is environmental compatibility ensured?
Our furnace lines use heat recovery, nitrogen cascades, and eco-design burners. Our electricity mix is largely based on Swiss hydropower and other renewable sources. CO₂ balance and energy consumption are measured, reported, and verified annually by external auditors.
