Carbide Inserts Designed for Better Heat Resistance and More Predictable Wear When Machining Steel

Sandvik Coromant is upgrading its range of turning inserts for machining ISO P steels. The tooling specialist has launched two new carbide grades designed for external and internal machining of low-alloyed and unalloyed steels. The new inserts, called GC4415 and GC4425, deliver increased toughness, heat resistance and predictable wear.

GC4415 and GC4425 are ideal for manufacturers operating in mass and batch production setups machining low-alloyed (P 2.1 to 2.6) and unalloyed (P 1.1 to 1.5) steels, respectively.

Grade GC4425 features improved wear, heat resistance and toughness, which significantly expands the application range. Both it and GC4415 can be used from finishing to roughing in applications with continuous cuts and light interruptions.

Meanwhile, GC4415 is designed to complement GC4425 when enhanced performance and more heat resistance are needed. In addition, the materials' new post-treatment has been found to boost performance in intermittent cutting operations, avoiding any sudden breakages and enabling both insert grades to outperform over a broad application range.

"Generally speaking, every manufacturer wants to achieve the following goals: increased metal removal rates, more pieces per edge, reduced cycle times, minimized waste and optimized inventory use," said Johan Anderstedt, Global Product Manager Turning at Sandvik Coromant.

"For manufacturers with a batch production setup, this also means having the flexibility to machine multiple steel materials with the same grade. Our new GC4415 and GC4425 grades can help you achieve this -- even with tough and complex ISO P materials."
