Nitronic-60

Introduction to Nitronic 60

Nitronic 60® is a wear-resistant, high-temperature stainless steel alloy, known for its exceptional galling resistance and ability to perform under extreme mechanical and thermal stress. While its durability makes it valuable in aerospace and automotive applications, its tendency to harden during cutting, and toughness create machining challenges, including high cutting forces, tool wear, and poor chip control.

Nitronic 60 provides oxidation resistance, uniform corrosion resistance, and crevice corrosion resistance, making it ideal for critical applications in the aerospace, automotive, and precision engineering sectors. Its mechanical properties, including high tensile strength and superior metal wear resistance, contribute to its reliability but add complexity to machining processes.

Exactaform’s high-performance carbide tools are engineered to handle the abrasive nature of Nitronic 60, providing improved wear resistance, optimised cutting geometries, and longer tool life. Our advanced cutting solutions effectively manage high work-hardening rates, ensuring efficient chip control, enhanced cutting process stability, and superior surface finishes. Whether machining for commercial applications or high-performance engineering materials, Exactaform’s tools maximise efficiency, precision, and tool longevity.

What Tool Groups Can You Use to Machine Nitronic 60?

Machining Nitronic 60 requires robust cutting tools due to its high work-hardening rate and resistance to deformation.

  • Carbide Tools:
    The best option for machining Nitronic 60, offering high wear resistance, heat stability, and improved tool life. Coated carbide tools can enhance heat dissipation and reduce built-up edge (BUE) formation. 

Maintaining low cutting speeds, high feed rates, and aggressive chip thinning strategies helps control heat buildup and prevent excessive tool wear. These machining techniques also minimise residual stresses, optimise performance metals machining, and extend tool longevity in demanding applications.

Exactaform’s cutting solutions are designed to handle the extreme temperature impact of Nitronic 60, retaining strength at elevated temperatures while ensuring efficiency and precision in high-performance machining.
