Harvester knives



We offer you the advantage of our long experience in materials, thermal sprayed coatings and heat treatments:
- Carbon steel, alloy steel,
- High-level quality of the cutting part
- Longer lifespan, anti-wear coating (tungsten carbide)
- less fuel consumption


According to your needs, we use carbon steel or alloy steel. The main elements of alloy are chromium, vanadium, manganese and boron. The steel is carefully selected to meet the strictest requirements in terms of the wear-resistance and the cutting ability. Our steel is carefully chosen. The different added elements provide superior hardness and also increase the cutting edge durability and improve the wear-resistance.


Heat Treatment:

Our blades receive quenching and tempering heat treatments. This increases their hardness and consequently, their lifespan. In addition, we perform double-heat treatments. This process provides the entire part with high impact strength and further reinforces the hardness of the cutting edge. Heat treatments are characterised by hardness measurements (and/or metallographic analysis), carried out internally.


Company standard:

More than 15 years ago Deguy-Conge initiated a quality approach to increase customer satisfaction.
We are currently ISO 9001 certified by AFNOR (major certification body in France).
