Hardening of File

Hardening of File

File Induction Hardening

A file is a hand cutting tool made of hardened steel for metalworking. Files are the most used tool among hardware tools.

Modern files are generally made from carbon steel that has been rolled, forged, annealed, ground, chopped and quenched. The file is made of t12 steel with a hardness of 62 to 64 after surface quenching.

Due to the high brittleness, the files quenched by traditional heating methods are prone to produce debris during use, which affects the service life. Using the characteristics of rapid induction heating to heat and quench the file can improve its toughness and prolong its service life. Induction hardening can ensure the hardness and wear resistance of the file, thereby improving the performance of the file.
