1.76C 7.8Cr-2.2Mo-1.1V Low Alloy Steel

This is a high-carbon tool steel heavily alloyed with chromium, molybdenum, vanadium, and cobalt—a composition typical of premium die steels and high-speed cutting tool alloys. The high carbon content (1.76%) combined with substantial chromium (7.8%) and molybdenum (2.2%) provides excellent hardness and wear resistance, while vanadium (1.1%) and cobalt (4.63%) enhance toughness and hot hardness. This material is found in demanding applications requiring superior edge retention and dimensional stability under thermal and mechanical stress, particularly where tool life and precision are critical economic factors; it competes with standard tool steels by offering enhanced performance in high-temperature or high-wear environments at the cost of reduced toughness and machinability.
