Applications
Circular saws for timber, saws for non-ferrous. Machine saws, measuring tools, tools for wood working (axes, kinvesp, punches, guide rods, twist drills, reamers, ejector pins, dentist's drills).

Heat Treatment
Annealing
710 to 850 °C
Cool slowly in furnace. This will produce a maximum Brinell hardness of 220.

Stress Relieving
To remove machining stresses should be carried out by heating to approx. 650 °C, holding for 1-2 hours at heat, followed by air cooling.

Hardening
810 to 840 °C
quenching in water/oil
hardness: 64-66 HRC

Tempering
tempering temperature 100°C: 64HRC
tempering temperature 200°C: 62HRC
tempering temperature 300°C: 57HRC
tempering temperature 400°C: 51HRC
tempering temperature 500°C: 44HRC
