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.
Tungsten-carbide inserts. Carbide is more expensive per unit than other typical tool materials, and it is more brittle, making it susceptible to chipping and breaking. To offset these problems, the carbide cutting tip itself is often in the form of a small insert for a larger tipped tool whose shank is made of another material, usually carbon ...

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 replacement for the S-SAPI in U.S. Army, the Enhanced Side Ballistic Inserts (ESBI, E-SBI), originally had only the 7 in × 8 in (180 mm × 200 mm) size, Small and medium were added later on. [14] The counterpart of the ESBI used by the U.S. Marines is called Enhanced Side Small Arms Protective Inserts (Enhanced S‐SAPI, Side ESAPI). [15]
1.11–1.30% carbon: files, small drills, lathe tools, razor blades, and other light-duty applications where more wear resistance is required without great toughness. Steel of about 0.8% C gets as hard as steel with more carbon, but the free iron carbide particles in 1% or 1.25% carbon steel make it hold an edge better.
