Stellite is a __________ material.

ANS:D - non ferrous cast alloy cutting tool

Stellite is a non-ferrous cast alloy cutting tool. Stellite is a trademarked name for a group of cobalt-chromium alloys with various other elements such as tungsten, molybdenum, and carbon. It is known for its exceptional wear resistance, high temperature strength, and corrosion resistance. Stellite alloys are often used in applications requiring high wear resistance, such as cutting tools, saw teeth, valves, and turbine blades. While Stellite contains cobalt, which is a ferrous element, it is classified as a non-ferrous alloy due to its composition primarily consisting of cobalt and chromium, with other non-ferrous elements added for alloying purposes. Therefore, Stellite is considered a non-ferrous cast alloy, specifically used as a cutting tool material.
