EN36A/15NiCr13/X3312H high-quality hot forged steel rings
Description:
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.
APPLICATIONS:
Heavy Duty Bushings, Collets, Conveyor Pins, Heavy Duty Gears, King 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 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.
Certificate of Quality: issued in English, in addition the normal terms, production process, the mechanical property (yield strength, tensile strength, elongation and hardness), forged ratio, UT test result, Grain size, heat treatment methods and the sample of is shown on the Certificate of Quality.
Marking: Heat No. will be cold stamped and Steel grade, diameter (mm), length (mm), and the manufacturer LOGO and weight (kg) is painted
