EN3 is commonly supplied bright drawn or as rolled. If annealing is required heat to 880-910°C, furnace cool.

As a low carbon steel EN3 is not ideally suited for heat treatment (EN8 or EN9 may be a better suited option). If hardening is required heat to a temperature of 880-910°C. Quench in water and temper.

When hardening EN3 heat treatment temperatures, including rate of heating, cooling and soaking times will vary due to factors such as the shape and size of each 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 EN3 carbon steel.

EN3 steel is commonly available with cast and analysis certificate or a certificate of conformity, please request when placing any orders.

EN3 is supplied in accordance with our ISO 9001:2015 registration.
