Typical Analysis: C 1.00, Mn .40, Si .20 W-1 Tool Steel is a general purpose water-hardening tool steel with a 1.00% Carbon content. It offers an excellent combination of physical properties with an outer case that is abrasion resistant in the 60 Rockwell "C" range with a soft, ductile inner core. W-1 is the easiest of all steels to machine with a machinability rating of 100 as a basis for comparison with other tool steels. Heat slowly to 1450° F. Hold 20 minutes per inch of greatest cross-section after tool reaches furnace temperature (minimum holding time-20 minutes). Quench in water or 10%: brine solution to 150/200°F. Temper immediately 2 hours per inch of greatest cross-section at temperatures shown to achieve the desired hardness.. LIMITED QUANTITY
