Low Alloy Nitriding Steel

32 CDV 13 in the French AIR 9160 aeronautical specifications is a 3% Cr-Mo-V nitriding steel offering a tensile strength of up to over 1,300 MPa and which develops a hard (around 850 HV), wear resistant surface after nitriding treatment.

The alloy is usually produced by single electric melting and vacuum degassing but is also available as a vacuum arc re-melted (VAR) version designated with the prefix (E). Material is ultrasonically tested. The alloy can be employed for high strength non-nitrided parts or for nitrided components where high mechanical properties are required in the core. Bars are usually supplied in the annealed condition.

Heat Treatment:

Final heat treatment consists of hardening at 950°C (oil quench) followed by tempering at a temperature appropriate to the balance of strength and ductility required (refer to published standard and table below).
