Sandvik Bioline 20AP is a hardenable, free-cutting carbon steel combining excellent machining properties, high hardness and dimensional stability during hardening. Very suitable for long narrow components with tight tolerances such as shafts, dental burrs and other fine mechanical components.
Service temperature -50 to +100 ℃. Prolonged service at elevated temperatures causes decreased hardness when used in the hardened and tempered condition.
