Ohio State University was the first to develop Al 2 O 3 based cermets with high stress rupture strengths around 1200 °C. Kennametal, a metal-working and tool company based in Latrobe, PA, USA, developed the first titanium carbide cermet with a 19 megapascals (2,800 psi) and 100-hour stress-to-rupture strength at 980 °C. Jet engines operate at ...
Stellite alloys are a family of completely non-magnetic and corrosion-resistant cobalt alloys of various compositions that have been optimised for different uses. Stellite alloys are suited for cutting tools, an example is Stellite 100, because this alloy is quite hard, maintains a good cutting edge at high temperature, and resists hardening and annealing.
Kennametal was founded in 1938 by Philip M. McKenna in the Latrobe, Pennsylvania area. [3] [4] The company evolved from Vanadium Alloys Steel Company (VASCO), founded in 1910 by the McKenna family with its headquarters in Latrobe, Pennsylvania. While research director of VASCO, metallurgist Philip McKenna developed and received a patent for a ...

The coefficient of thermal expansion of cemented tungsten carbide is found to vary with the amount of cobalt used as a metal binder. For 5.9% cobalt samples, a coefficient of 4.4 μm/m·K was measured, whereas 13% cobalt samples have a coefficient of around 5.0 μm/m·K.

In addition to the descriptive steel grade naming system indicated above, within EN 10027-2 is defined a system for creating unique steel grade numbers. While less descriptive and intuitive than the grand names they are easier to tabulate and use in data processing applications. The number is in the following format: x.yyzz(zz)
