The IS6 grade was developed in order to increase productivity in cast iron turning, as a complementary grade to the IS8 and IS80. IS6 can be used also for high productivity in rough turning of steel mill rolls composed of high-Cr steel, HSS (High Speed Steel) and adamite. The SiAlON material is characterized by high hardness, combined with moderate fracture toughness and excellent thermal resistance. These characteristics are achieved by a manufacturing technology of precisely-controlled alloy composition and a special sintering process that enables the IS6 grade to function at higher cutting speeds than the SiN-based ceramic grades.

Recommended Cutting Parameters:
Roughing: 500 - 1,000 m/min
Finishing: 600 - 1,200 m/min
