080M40 / 080A42 / EN8D - ACTON BRIGHT STEEL TECHNICAL GUIDE

Steel Description

080M40 / 080A42 / EN8D is a medium “ 40” carbon steel that is supplied in the bright drawn or turned bar condition. It has reasonable tensile strength where better properties than mild steel are required and can be heat treated to provide a good surface hardness with moderate wear resistance by flame or induction hardening processes, but welding is not recommended. 080M40 / 080a42 / EN8D is readily machinable and is used for axles, pins, shafts, spindles and studs.Where higher machining speeds and a better surface finish is required, we can also supply a sulphurised semi freecutting 212A42 / EN8DM on which we have a technical guide.
