Material Notes:
Type SP-100 is characterized by its exceptional hardenability. It is particularly suited where high strengths are desired in relatively heavy casting sections. In the as-cast condition it has a pearlitic structure. Any hardness value may be obtained, ranging from that of a free machinable iron to that of the fully hardenable tool steel. SH-100 oil quenched from 1650°F and drawn at 750°F results in good combination of harness, strength and toughness.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.
