UNI C 21 B KB Heat Treatments
- Material shall be supplied spheroidize annealed (Annealed). Response to Heat Treatment: The hardness value contained in the mechanical properties table for the Hardened condition is the minimum value required in the centre of a test piece with a maximum diameter of 9mm following hardening by oil quenching from 890°C. The hardness value shown for the Hardened and Tempered (H+T) condition is that required after final heat treatment.
