Cobalt obstructs critical grain growth and above all, main- tains an excellent degree of hardness at high operating temperatures. These characteristics are very important when cutting very high-alloy materials such as stainless steel and very hard metals, which tend to develop high temperatures in the cutting zone. Hardness of this steel: 65 ± 1HRC. ' Steam treated ' is a surface modification by CO 2 oxidation. Circular saws are let to tempering in overheated steam of arround 350 °C. This results to: – Microporisity arised on surface enables better coolant distribution – Surface hardness of 900 HV. – Extremely fine surface layer decreases the friction (antifriction). Coefficient friction 0.60.
