  
                The most versatile of the tool steels. Often refered to as the "General Purpose Tool Room Steel." Excellent saftey in hardening, little distortional change in heat treatment. 
                HEAT TREATMENT 
                    Forging: Slowly to 1850F-1950F Cool slowly on ashes, dry lime or other insulating material. 
                Normalizing: Do not normalize. 
                Annealing: Heat slowly to: 1450 F Furnace cool 20 per hour to 900 F, Then air cool. 
                Average brinell hardness 202. 
                Hardening: 1475 F (Quench in oil) Temper immediatly after quench.
