In 1868 English metallurgist Robert Forester Mushet developed Mushet steel, considered the forerunner of modern high-speed steels. It consisted of 2% carbon, 2.5% manganese, and 7% tungsten. The major advantage of this steel was that it hardened when air cooled from a temperature at which most steels had to be quenched for hardening. Over the next 30 years, the most significant change was the replacement of manganese with chromium. WebJul 6, 2010 · For cutting tool applications PM 60 offers a unique combination of red hardness and strong toughness compared to all other high-speed steels that other materials don’t have. In times of high-carbon tool steel scrap, PM 60 is the best alternative. Other Known Names: ASP 2060, HS 6-7-6-10. Griggs Steel Color Code: Orange.
WebThe machinability of M1 molybdenum high speed tool steels is 50% of that of the W group or water-hardening low alloy tool steels. Heat Treatment M1 steels are preheated at 760°C (1400°F ) before heat treatment. They are then heated rapidly to 1190°C (2175°F) for 3 to 5 min followed by oil-quenching, salt bathing or cooling in air.
