We produce the thermocouple protection tube for many years which in made of high temperature metal ceramics and stellite alloy.
Stellite alloys display outstanding hardness and toughness, and are also usually very resistant to corrosion. Typically, a Stellite part is precisely cast so that only minimal machining is necessary. Stellite is more often machined by grinding, rather than by cutting. The alloys also tend to have extremely high melting points due to the cobalt and chromium content.
