EN36
Technical Data
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 core.

Heat Treatment - Carburising Temperature
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.
Tempering:
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 Rockwell C60/62.
