| Type K-295 is used for applications such as gears requiring high contact rolling and tooth bending fatigue properties. Type K-295 also possess high fracture toughness impact strength. Excellent founding properties enable more accurate castings with savings in machine stock required. Damping capacity and notch sensitivity are superior to steel castings and forgings. Self-lubricating properties make Type K-405 ideal for wear conditions involving minimal lubrication. General Meehanite information - Meehanite metal is first melted to a definite degree of undercooling or constitution which is related to the section of the casting to be poured and the range of physical properties such as tensile strength and hardness required. Nucleation with patented mixtures of graphitizing agents results in the removal of undercooling, in the controlled precipitation of graphite and in a fine grained eutectic cell structure which determines the density and physical integrity of the casting. Ordinary cast irons made to chemical specifications which do not include the benefit of controlled undercooling are influenced by mass effect to a maximum degree and for this and other reasons cannot be considered an equivalent to Meehanite metal.
