EN36 case hardening steel stockholders and suppliers, delivering to the whole of the South. EN36 is a 3% nickel, chromium, molybdenum grade. Carburised EN36 gives a hard case with a strong core, whilst retaining a remarkable degree of toughness.
- 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.
- For optimum toughness temper at low temperatures for a minimum of 2 hours. The case hardness should be in the region of 60-62HRc.
- 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 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.
