Type HS compares very favorably from a strength standpoint with any heat resisting metal and is recommended for applications at temperatures up to 1800°F under both conditions of cyclic and continuous heating without thermal shock. Compositional adjustments are made to suit the exact service conditions. It machines easily and provides maximum resistance to scaling and growth.
Type HSV is an iron developed essentially for engineering parts that are subjected to long continuous heating at temperatures up to 1600°F.
It has been designed to have the maximum load bearing ability.
Type HR is a strong, dense iron of high rigidity and excellent resistance to scaling under most conditions. It is non-growing for temperatures up to 1350°F and possesses good load carrying ability.
Type HE is a freely machinable material in the as-cast condition. Withstands rapid heating and cooling without premature failure, offers good dimensional stability and a good range of strength properties.
