EN8 is an unalloyed medium carbon steel grade with reasonable tensile strength. It is normally supplied in cold-drawn or as-rolled conditions. Tensile properties can vary but are usually between 500-800 N/mm². EN8 is widely used for applications that require better properties than mild steel but does not justify the costs of alloy steel. EN8 can be flame or induction hardened to produce a good surface hardness with moderate wear resistance. EN8 is available from stock in the bar and can be cut to your requirements.
Hot Rolled
EN8 steel material is suitable for all general engineering applications requiring a higher strength than mild steel such as:
• General-Purpose Axles
• Shafts
• Gears
• Bolts and Studs
• Spindles
• Automotive and General Engineering Components
• Other General Engineering Parts etc.
