O-1 OIL HARDENING DRILL ROD ROUND Carbon - .95%    Manganese - 1.20%    Silicon - .25% For ¼" round and larger, we carry oil hardening drill rod rather than water hardening. The O-1 in this size range is characterized by good machineability, smooth finish as well as superior dimensional stability and excellent hardening characteristics. We recommend it for use in dies, tools, parts, and punches. Excellent for general use in the shop. HARDENING: Heat slowly to 1475° F. - 1525° F. If a controlled furnace is not available, use 1500° Tempilaq. Hold at this temperature for a few seconds then quench in a light quenching oil. TEMPERING: Temper immediately. The following hardness table is for a one hour draw after oil quenching at 1500° F. Degrees F. Rockwell C Hardness As Hardened 63 - 65 300° 63 - 64 400° 61 - 62 500° 58 - 60 600° 54 - 56 700° 51 - 53 800° 46 - 48 900° 43 - 45
