|O1 Oil Hardening Tool Steel|
Technical Data Sheet
O1 Tool Steel is a general purpose oil-hardening tool and die steel. Normal care in heat treatment gives good results in hardening and produces small dimensional changes. O1 has good abrasion resistance and sufficient toughness for a wide variety of tool and die applications.
TYPICAL CHEMISTRY: C 0.90 Mn 1.20 V 0.20 W 0.50 Cr 0.50
MACHINABILITY When properly annealed, O1 has a machinability rating of 90 when compared to a 1% Carbon Steel rated at 100.
DIMENSIONAL STABILITY : When oil quenched from the proper hardening temperature, this grade can be expected to expand approximately .0015 in. per in. Note: Distortion (bending, bowing and twisting) and part geometry can add to the variations in movement of a part being hardened.
THERMAL CYCLING: In order to avoid decarburization, this grade should be annealed and/or hardened in a controlled neutral atmosphere, vacuum or neutral salt furnace environment.
The values shown in this data sheet are to be used as a guide for estimating purposes only.
