Sandvik Finemac is a lead-free, hardenable, free-cutting carbon steel characterized by excellent machinability and high hardness, high wear resistance and exceptional dimensional stability after hardening. Hardening operations are very much simplified compared to Sandvik 20AP, owing to the wider temperature and time range available using Sandvik Finemac. This results in significantly reduced failure rates during hardening. Sandvik Finemac also exhibits very good cold heading properties. The material is suitable for long, narrow components with tight tolerances. Service temperature 50 to 100°C (55 to 210 F). Prolonged service at elevated temperatures causes decreased hardness when used in the hardened and tempered condition.Information provided by Sandvik |
