Applications

655M13 is a carburising steel grade 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.

Carbon 0.10-0.16% Nickel 3.00-3.75%
Manganese 0.35-0.60% Chromium 0.70-1.00%
Silicon 0.10-0.35% Sulphur 0.040% max
Phosphorous 0.035% max

Carburising and case hardening will give a hard wear resisting surface and a tough core strength to 655M13. Ensure that surfaces are free from dirt and grease, and of low sulphur content. Case hardening can be carried out in salt baths with selected content depending on the type of salt and the depth of penetration required. Other considerations during the heat treatment process include the type of furnace, quenching medium and work piece transfer facilities. Time, temperatures and salt selection will be advised by your heat treatment provider.

If it is necessary to soften the 655M13 for machining between the carburising and subsequent heat treatment stages, heat to 640-650°C. Soak at this temperature for one to two 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 655M13 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 655M13 case hardening steel.

655M13 case hardening steel is available with BS EN 10204 3.1 mill certificate, please request when placing any orders.
