SANDVIK COROMANT introduced a new grade in its steel turning series – Grade GC4405 – for high metal removal rates in stable conditions, particularly in harder steels. The option to machine dry in softer steels also offers opportunities for more sustainable machining.
In addition to the new GC4405, Sandvik Coromant recently introduced the GC4425 and GC4415 steel turning grades. These grades have been fully refined, delivering an average 25 percent increase in tool life compared to the previous grades.
Grade GC4425 delivers wear-resistance, heat-resistance, and toughness in a wide application range, while grade GC4415 complements GC4425 with enhanced performance when more heat-resistance is needed.
Grade GC4405 should be applied as a high-feed productivity optimizer with high metal-removal rates in stable conditions with demanding plastic deformation properties.
Among the features offered by the GC4405 is a new carbide substrate with optimized microstructure, which reduces plastic deformation in high-feed applications. The increase in plastic deformation resistance has enabled a drastic expansion in the application range toward harder steels and higher productivity compared to the existing grade GC4305.
GC4405 features the second-generation Inveio® technology coating, which is designed to combat crater wear common to P05 applications, with an alumina coating where the crystals are aligned even more vertically toward the top surface to improve wear resistance, offering more consistent quality and performance.
The GC4405 offers an increase in productivity and tool life, particularly when machining steels above 300 HB. The new grade is also suitable for machining softer steels without the need for coolant, offering substantial opportunities for more sustainable machining.
