Material Notes:

R.D.S. tool steel is an oil hardening die steel which combines extreme toughness with very little size change when heat treated. It is available as a DeCarb-Free product. DCF bars have been cold finished in the mill, eliminating the need for bar bark removal.Applications: Hobs, Collets, Punches, Forming Rolls, Blanking or forming dies, Thread roller dies, Embossing dies, Shear blades, Stamps, Swaging dies, Slitting shears, Slitting cutters, Clutch parts, Pawls, Dogs, Stops, Knuckle Pins, Spindles, Fingers, Indexing pins, Clutch pinsInformation provided by Carpenter Technology Corporation.R.D.S.® is a registered trademark of Carpenter Technology Corporation.
