Abstract

A die casting die including a stainless steel comprising, by weight, 13 to 16 percent chromium, 0 to less than 0.1 percent carbon, 10 to 17 percent cobalt, 2 to 6 percent molybdenum, 2 to 5 percent nickel, and 0 to 1.5 percent titanium. High strength, high toughness stainless steels having the indicated composition may exhibit favorable thermal fatigue resistance, Rockwell C hardness greater than 40, and Charpy impact toughness greater than 25 ft-lbs.
