Material Notes:
Type SP-80 possesses in the as-cast condition more than twice the strength of conventional gray cast iron in combination with exceptional toughness. It has a predominantly pearlitic structure, is readily machinable and responds easily to surface hardening by chill casting or by flame or electric induction heat treatment.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.Information provided by Meehanite Marketing Association.
