About
EN3 is a low-carbon steel, sometimes called mild steel.
This steel is used for general engineering and manufacturing components with low tensile strength requirements like flanges, bushes, spacers, shafts, bolts, nuts, and light-duty pulleys.
EN3 is a low carbon, tensile strength steel with a carbon content between 0.16% and 0.24% carbon.
It is easy to machine and weld. EN3 can also be case hardened, resistant to severe weather conditions, and suitable for high-stress applications.
Special Steels sells EN3 round bar. We cut the quantity of EN3 to the tolerance required for precision engineering and manufacturing at a large volume.
We also offer machine preparation and deliveries.

About
EN8 is a medium carbon steel that Special Steels supplies as either a round bar or a bright bar.
This is typically used when mild steel does not provide sufficient surface hardening potential. One can manufacture axles, driveshafts, crankshafts, connecting rods, high tensile bolts, studs, propeller shaft joints, rifle barrels, and induction hardened pins from EN8 because it is more cost-effective than alloy steels.
EN8 is a medium carbon steel that can be machined, welded, and suitable for surface hardening treatments like induction and flame hardening. EN8 contains between 0.36% and 0.44% carbon.
It can be machined and welded because the carbon content is low enough but has a high enough carbon content to allow surface hardening. It is more affordable than alloy steel while providing the same benefits.
Special Steels sells EN8 round bar and bright bar. We cut the quantity of EN8 to the tolerance required for precision engineering and manufacturing.
