Type CC is a general utility material providing good corrosive resistance. It can be used for slightly acid solutions, alkali solutions at temperatures up to 150°F and concentrated sulfuric acid at temperatures up to 250°F.

Type CR is an austenitic material especially designed to meet a wide variety of corrosion, wear and heat applications. It has flake graphite and chemical analysis conforming to ASTM Specification A-436-61T.

Type CRS is an austenitic material with graphite in the nodular form. It conforms to ASTM designation A439-60T and provides much higher strength than type CR with excellent resistance to corrosion, wear and heat.

Both type CR and CRS are recommended for components which involve handling acid and alkali solution at temperatures up to 1300°F; for abrasive slurries, salt water and other heat and wear applications with or without corrosive media.

Type CHS is a higher strength material with good shock resistance. Compositional adjustments are made to suit exact service requirements. Recommended for use for components subjected to concentrated sulfuric acid or oleum.
