EN3 Steel
EN3 Engineering steel
EN3A and EN3B are general engineering steels, suitable in applications where heavy stresses and heat treatment are not involved, such as welded and riveted structures, forgings, machined parts, and hot pressing. We Stock this in a range of sizes and shapes.
It is a bright drawn, or turned, mild steel with good machinability. Ideal for use in a variety of general engineering applications. EN3A and EN3B can be case hardened and is normally supplied in the as drawn / as a turned condition. EN3A and EN3B steel will withstand a moderate amount of cold deformation and only offers low strength but good machinability. The material has good weldability characteristics however it has poor hardenability.

Applications
EN3 steel is widely used for a variety of applications in the used in the automotive and engineering industries for toolholders and other such components. Typical applications such as valve bodies, pumps and fittings, Shaft, the high load of wheel, bolts, double-headed bolts, gears, etc
Analysis
| Carbon | 0.25% max | Phosphorous | 0.06% max |
| Manganese | 1.00% max | Sulphur | 0.06% max |
| Silicon | 0.05-0.35% |
Annealing
EN3 is commonly supplied bright drawn or as rolled. If annealing is required heat to 880-910°C, furnace cool.
Hardening
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.
Heat Treatment
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.
