Advantage of our crankshaft:
1. Our crankshaft use the highest quality E4340 Aircraft quality Cr-Ni-Mo alloy billet steel.
2. Triple heat treated for extreme strength, toughness & durability.
3. Ion-plasma nitride for superior journal surface hardness & wear resistance.
4. Heat treatment, quenching Increasing the strength (surface treatment,
e.g. Induction hardening, fillet rolling or shot peening, etc.)
5. Dimensional measurement,Full NDT inspection (Magnaflux and Hardness),ultrasonic testing,
crack detection and material testing.
6. Fatigue strength testing
7. Torsion and bending fatigue testing
About our quality control:
We have passed quality control certification system of ISO9000,TS16949 which are main quality certificate.
Quality Control equipments include Spectrometer, Microscope, Durometers, Magnetic particle crack detectors,
Perfilometer, Roughness test machine, Residual stress inspection etc.applied on every production step.
HC Crankshafts are guaranteed for 12 months after arming in engine.If in this period the crankshaft is broken,
we will one compensable three.
