EN36C Carbon Steel
Grade Introduction:
EN36C steel bright bar is a Nickel Chromium Case hardening steel which is suitable for deep hardening to develop a touch core is suitable for gears, cams rollers available in diameters only. EN36C is a carburizing steel grade with very high surface strength with a soft but strong core. The material retains a remarkable degree of toughness. With high tensile strength, EN36C is used in the production of numerous high strength parts including crankshafts in the automotive and aerospace sector. En36C is used specifically in heavy duty and highly stressed applications due to its harden ability toughness and high core strength. EN36C also offers excellent fatigue resistance. EN36C gives a hard case with a strong core, whilst retaining a remarkable degree of toughness.
Grade Application
As a carburizing steel grade it is suitable for roller and ball bearings of extra light section, aero plane 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 collects.

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 EN36C 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 EN36C case hardening steel.

Hardening
Harden at 760/780°C then quench in oil.
Tempering
Temper in oil at temperature of 150/200°C this will alleviate stresses and the risks of cracking.
Machinability
En36C offers very good machinability and weldability when supplied in the annealed condition, although when welded the material should be stress relieved after cooling. Welding is not however recommended in the heat treated or carburized condition. Machinability options including turning, milling, drilling and tapping are all suitable as long as the tool type, feeds and speeds are used in accordance with the machine manufacturer’s recommendations.
Welding
Readily weldable in the annealed supplied condition.
