6.Property & Application:
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.
Case hardening will give a hard wear resisting surface and a tough
core strength EN36. Surfaces must be 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.
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.
