EN36A/15NiCr13/X3312H high-quality hot forged steel rings
EN36 is an alloy case hardening steel. Characteristics of the steel
are toughness arising from the use of nickel and a more uniform
hardness produced by the use of chromium. It is specifically
designed for carburising to give a very hard case with a strong

Pins, Ring Gears, Sprockets, Shafts, heavy-duty gears, collets etc.
Or can be used for high tensile applications uncarburised but
through hardened and tempered.

Heat to 890°C/920°C and soak for the necessary time to obtain the
desired carburised depth.
Single Quench Treatment:
Heat the carburised parts to 800/820°C and quench in oil.
Double Quench Treatment:
Heat the carburised parts to 850/880°C, cool in oil or air then re
heat to 760/780C and quench in oil.
After hardening temper at 150°C for 2 hours minimum, and allow to
cool in air to give a final surface hardness in the region of
