The following are the characteristics of each grade of spheroidal graphite alloy.

Ni-Resist D-2 – Has good resistance to corrosion,corrosion-erosion and frictional wear. Can be used at temperatures up to 760°C(1400°F). Applications are pumps, valves, compressors, turbocharger housings and exhaust gas manifolds used with Ni-Resist D-2W, a primary ductile grade.

Ni-Resist D-2W – Has similar properties and applications as Ni-Resist D-2, but with better weldability when proper procedures are followed.

Ni-Resist D-2B – Has higher chromium content which results in better corrosion and corrosion-erosion resistance than Ni-Resist D-2. Has similar applications to Ni-Resist D-2.

Nicrosilal Spheronic – Has improved corrosion resistance in dilute sulfuric acid and good high temperature stability. Used for pumps, valves and other castings requiring higher mechanical properties.

Ni-Resist D-2C – Used for pumps, valves, compressors and turbochargers where high ductility is desired.Because of good resistance to wet steam erosion, another important application is in steam turbines. Sometimes used for non-magnetic components. Is also used for some low temperature applications.

Ni-Resist D-2M – Maintains ambient temperature mechanical properties down to -170°C(-275°F). Major uses are for refrigeration and cryogenic equipment.

Ni-Resist D-3A – Suggested where a high degree of wear and galling resistance are required along with moderate amounts of thermal expansion.

Ni-Resist D-3 – Has good corrosion resistance at elevated temperatures. Excellent corrosion-erosion resistance in wet steam and salt slurries. Uses include pumps, valves, filter parts, exhaust gas manifolds and turbocharger housings.

Ni-Resist D-4A – Has excellent corrosion and corrosion-erosion resistance with superior high temperature properties. Finds uses in pumps, armatures, exhaust gas piping and turbocharger parts.

Ni-Resist D-4 – Corrosion, corrosion-erosion and heat resistant properties are superior to those of Ni-Resists D-2 and D-3. Applications are similar to Ni-Resist D-4A.

Ni-Resist D-5 – Is used where low thermal expansion is required. Applications include machine tool parts, scientific instruments and glass molds.

Ni-Resist D-5B – Has low thermal expansion with high levels of heat and corrosion resistance. Has good mechanical properties at elevated temperatures. Used for low pressure gas turbine housings, glass molds and other elevated temperature applications.

Ni-Resist D-5S – Has excellent resistance to growth and oxidation at temperatures up to 1050°C(1930°F).

Low coefficient of thermal expansion with good thermal shock resistance. Used in gas turbines, turbocharger housings, exhaust manifolds and hot pressing dies.

Ni-Resist D-6 – Is non-magnetic with good mechanical properties. Used for switch insulator flanges, terminals,ducts and turbine generator parts.
