This results to: – Very good mechanical characteristics and excellent strength with a hardness of 64 ± 1HRC. 'Steam treated' is a surface modification by CO2 oxidation. Circular saws are let to tempering in overheated steam of arround 662°F. 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. Cutting angles Movie METAL CIRCULAR SAW BLADES < 800 N 11 Index 10 9 OIL 8 7 6 5 4 3 2 1
