In the demanding world of automotive clutch diaphragms and precision electronic shutter components, the fatigue life of C67S (DIN 1.1231) is the dividing line between a high-performance system and a mechanical failure. Alloword delivers C67S strips that exceed EN 10132-4 standards, engineered for zero-defect manufacturing.

1. Why Alloword C67S? The Metallurgy of Reliability
Ordinary high-carbon steel often suffers from surface decarburization or uneven carbide distribution, leading to premature brittle fracture.

Decarburization-Free Surface: Powered by our Austrian Ebner H2-Bell Type Annealing system, Alloword achieves a near-zero decarburization layer. This preserves maximum surface hardness, effectively extending the fatigue limit by 15-20% compared to conventional nitrogen annealing.

Optimized Microstructure: We achieve a spheroidization rate of ≥95%. This uniform distribution of fine carbides ensures superior formability during complex stamping and bending, preventing micro-cracks in your final products.

2. Dimensional Precision: The Power of ±0.002mm
In automated high-speed stamping lines, thickness variation is the enemy of tool life and load consistency.

Sendzimir 20-High Mill: Alloword’s advanced rolling technology holds tolerances as tight as ±0.002mm.

The Result: Whether it’s a valve shim or a clutch diaphragm, you get consistent spring force across every batch, minimizing machine downtime and maximizing your yield.

3. High-Demand Applications
Alloword C67S (1.1231) is the trusted choice for Global Tier-1 suppliers:

Automotive Power Systems: Clutch diaphragm springs, valve shims, and disc springs (Belleville washers) requiring extreme fatigue resistance.

Seating & Interior: Seat recliner torsion springs and high-strength locking mechanisms.

Precision Electronics: Camera shutter leaves and micro-motor springs requiring ultra-thin gauges and flat, tension-free surfaces.

4. Quality Assurance & Global Compliance
We understand that international trade is built on trust and documentation.

Full Traceability: Every shipment from Alloword is accompanied by a Material Test Certificate (EN 10204 3.1).
