Diameter

Applications

As a carburising steel grade it is suitable for roller and ball bearings of extra light section, aeroplane and motor crankshafts requiring hard surfaces for roller paths, connecting rods with case-hardened ends, as well as highly stressed gudgeon pins, gears and certain types of collets.


Carburising / Case Hardening

Case hardening will give a hard wear resisting surface and a tough core strength to the steel. Case hardening temperatures range from 860-960°C, followed by rapid quenching which will determine the resulting hardness.


Tempering

For optimum toughness temper at low temperatures for a minimum of 2 hours. The case hardness should be in the region of 60-62HRc.

Softening

If it is necessary to soften the EN36 for machining between the carburising and subsequent heat treatment stages, heat to 640-650°C. Soak at this temperature for 1 to 2 hours and cool slowly in the furnace or in air.


Heat Treatment

Heat treatment temperatures, including rate of heating, cooling and soaking times will vary due to factors such as the shape and size of each EN36 steel component. Other considerations during the heat treatment process include the type of furnace, quenching medium and work piece transfer facilities. Please consult your heat treatment provider for full guidance on heat treatment of EN36 case hardening steel.


Certification

EN36 case hardening steel is available with BS EN 10204 3.1 mill certificate, please request when placing any orders.
