GC1230: A Serendipitous Success Story

Stories7 October 2025

Since the successful introduction of GC1230, our innovative Zertivo® nano-multilayer PVD coating, we've witnessed unprecedented success across various material groups. Originally designed for ISO P alloy steel square shoulder milling applications, GC1230 has also excelled in ISO S materials, including Titanium alloys and Inconel billet materials.

Unmatched performance across materials

GC1230's performance in Titanium alloys (both clean and forged skin conditions) and Inconel billet materials is remarkable. This success is attributed to its improved edge line toughness, wear resistance, and coating adhesion. Unlike its predecessor, GC1130, GC1230 demonstrates exceptional versatility across multiple materials.

Adaptability in modern processes

For ISO S materials, GC1230 has proven effective in modern coolant-based processes, showcasing its ability to operate in both dry (preferable in steel) and wet conditions. This adaptability was not initially within our development scope, making this outcome a pleasant surprise for our global customer base, particularly in Aerospace, Defence, Pump & Valve, and Energy sectors.

Supporting productivity and sustainability

As industries strive for enhanced productivity and sustainability, GC1230 stands out as a solution aligned with these goals. Its durable nano-layered coating addresses key challenges in steel milling and other material groups by balancing heat resistance and durability. For manufacturers aiming to improve performance while meeting sustainability targets, GC1230 offers a practical and adaptable choice, supporting the industry's transition towards more efficient, sustainable practices on the shop floor.

Conclusion

GC1230's serendipitous success across various material groups highlights its versatility and reliability. As we continue to innovate, we are excited to see how GC1230 will further contribute to the productivity and sustainability goals of our diverse industry segments.
