Steel Alloys
In a second key advance in metallurgy Mushet invented 'R Mushet's Special Steel' (RMS) in 1868. It was both the first true tool steel and the first air-hardening steel. Previously, the only way to make steel hard enough for machine tools had been to quench it, by rapid cooling in water. Self-hardening (or tungsten) steel machine tools could run much faster and were able to cut harder metals than had been possible previously. RMS revolutionised the design of machine tools and the progress of industrial metalworking, and was the forerunner of high speed steel.

Famous quotes containing the word steel:
“Man you ought to see his plans for allsteel buildins. He’s got an idea the skyscraper of the future’ll be built of steel and glass. We’ve been experimenting with vitrous tile recently... crist-amighty some of his plans would knock you out... He’s got a great sayin about some Roman emperor who found Rome of brick and left it of marble. Well he says he’s found New York of brick an that he’s goin to leave it of steel... steel an glass.”
