Since 1973, Ahkemak Metallurgy has delivered reliable steel casting, stainless steel, gray cast iron and ductile iron solutions from its 4,000 m² facility in Konya. For defense, transportation, machinery, marine, automotive and construction applications, our quality backbone is built on rigorous NDT testing and spectrometer-driven chemistry control.
NDT: Choosing the Right Method for the Risk
Non-destructive testing finds surface and internal defects without harming the part:
- PT (Liquid Penetrant): Finest surface cracks; ideal after machining or welding.
- MT (Magnetic Particle): Surface/near-surface flaws in ferromagnetic steels; gears, flanges, frames.
- UT (Ultrasonic): Internal discontinuities in thick-section steel castings; fast acceptance checks.
- RT (Radiography): Volumetric defects such as porosity and shrinkage; safety-critical geometries.
We ensure calibrated equipment, proper surface prep and environmental controls, with acceptance criteria defined in the contract quality plan.
Spectrometer: Chemistry You Can Trust
Before/after melt, heat samples are analyzed by spectrometer to verify alloying elements. This enables:
- Target composition for steel, gray and ductile iron castings,
- Correct heat-treatment recipes,
- Full traceability (heat number) for each lot,
- Delivery of EN 10204 3.1 certificates and chemistry reports.
