080M40 Steel (EN8)
080M40 (EN8) is a medium carbon steel offering moderate strength.
Hardening is achieved through quenching and tempering but is often supplied untreated and normalised. With similarities to mild steel, this carbon steel has good machinability. As an unalloyed medium carbon steel, this grade is used in applications where better properties than mild steel are required but where the costs do not justify the purchase of a steel alloy.
- Case-hardened engineering steel
- For lightly stressed components
- Readily machinable and weldable
- Good dimensional stability
Also referred to as EN8 carbon steel, its equivalent grade under the previous BS 970: 1955 standard. This popular steel grade can be heat treated to offer superior surface hardness and good wear resistance by using induction or flame-hardening processes. Our material is a popular steel in the industry, with applications ranging from automotive to general engineering.
