   EN36 (655M13)

CARBURISING ENGINEERING STEEL

   PRODUCT OVERVIEW

EN36 (655M13) is a nickel-chromium-molybdenum based case hardening engineering steel which is specifically designed for carburising. The addition of nickel increases shock resistance and toughness whilst the chromium increases the materials hardenability giving it a uniformed hardness. Once hardened and carburised. EN36 can achieve a core strength of up to 1230 N/mm². EN36 (655M13) is used specifically in heavy duty and highly stressed applications due to its hardenability, toughness and high core strength. EN36 also offers excellent fatigue resistance.
   CARBURISED vs NON-CARBURISED

Following the carburising process, EN36 maintains a strong core whilst offering good toughness and be easily processed. EN36 is an adaptable material which offers excellent fatigue resistance and toughness. The material is usually supplied in the annealed condition which results in a hardness up to 255HB. It can be also be supplied in the un-carburised condition as an alternative. This results in a high tensile steel and if suitably hardened and tempered EN36 can be utilised in applications requiring good strength and toughness. EN36 can be nitrided in the un-carburised state for increased surface hardening but flame and induction hardening is not an option due to the material's low carbon content. In certain cases, it may be necessary to soften EN36 (655M13) after carburising and before heat treatment.
   MACHINABILITY

EN36 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 carburised condition. Machinability options including turning, milling, drilling and tapping are all suitable as long the tool type, feeds and speeds are used to the machine manufacturers recommendations.
   APPLICATIONS

EN32 (080M15) is a general engineering steel which is ideal for producing lightly stressed parts and components. Application examples include:

  • Aircraft and automotive crankshafts
  • Ball and roller bearings
  • Highly stressed gears, collets and gudgeon pins
  • Connecting rods with case hardened ends
  • Heavy duty gears, ring gears
  • Heavy duty bushes
  • Couplings and shafts
