ABSTRACT:
The invention provides a novel metallic composition and method of using the same. More particularly, the invention affords a tool steel and a method of using the tool steel. In one of the preferred embodiments the tool steel includes about 0.50 to about 0.65 percent by weight carbon, about 0.090 to about 1.45 percent by weight manganese, up to about 0.030 percent by weight phosphorus, about 0.035 to about 0.070 percent by weight sulfur, about 1.10 to about 1.90 percent by weight chromium, about 0.15 to about 0.40 percent by weight nickel, about 0.20 to about 0.40 percent by weight copper and balance percent by weight iron and impurities.
