EN32 Case Hardening Steel


EN32 case hardening steel stockholders and suppliers, delivering to the whole of the UK. This steel is an unalloyed low carbon grade. Components when carburised have a core strength range of 430-490N/mm² with a hard wear resistant surface case. It is a popular case hardening steel grade for general engineering, readily machineable and weldeable in its supply condition. EN32 is a low tensile steel suited for lightly stressed components.

Applications

Commonly used for general engineering lightly stressed applications that are subject to wear, EN32 is suitable for applications such as collets, cams, rollers, bushes, spindles, and gears.


Carbon0.10-0.18%Phosphorous0.05% max
Manganese0.60-1.00%Sulphur0.05% max
Silicon0.05-0.35%

EN32 is suited for carburising and case hardening, 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.


Harden at a temperature of 760-780°C. Quench in water.


Tempering is recommended for stress relief and maximum case toughness. Tempering range from 150-200°C.

Heat treatment temperatures, including rate of heating, cooling and soaking times will vary due to factors such as the shape and size of each 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 case hardening steel grades.


EN32 case hardening steel is commonly available with cast and analysis certificate of a certificate of conformity, please request when placing any orders.
