Cordite's use was further developed in the early years of World War II, for launching 2-inch and 3-inch diameter non-rotated, anti-aircraft projectiles. Small cordite rocket charges were also developed for ejector seats made by the Martin-Baker Company. Cordite is now obsolete and it is no longer produced. It has been replaced by other propellants, such as the Improved Military Rifle (IMR) line of extruded powder or the WC844 ball propellant currently in use in the 5.56 x 45 mm NATO.
Cementite is iron carbide with the formula Fe 3 C, and an orthorhombic crystal structure. It is a hard, brittle material, essentially a ceramic in its pure form.It forms directly from the melt in the case of white cast iron.ementite contains 6.67% Carbon by weight; thus above that carbon content in the Fe-C phase system, the alloy is no longer steel or cast iron, as all of the available iron is contained in cementite. Cementite mixes with ferrite, the other product of austenite, to form lamellar structures called pearlite and bainite.
