03Services
Our services
Anadolu İndüksiyon brings years of know-how and experience. From induction surface hardening to vacuum hardening, from case hardening to nitriding: every heat-treatment step under one roof.
- 01 Induction Hardening Induction surface hardening from 20 to 500 kW in Gebze: a hard surface and tough core on shafts, gears and wear zones, with low distortion.
- 02 Tempering Tempering for hardened steel parts: relieves internal stresses, restores toughness and sets the hardness to the value on your drawing.
- 03 Vacuum Hardening Vacuum hardening for tool, die and martensitic stainless steels: a clean surface with no oxidation or decarburisation, and low distortion.
- 04 Normalising Normalising for forged, rolled, cast and welded steel parts: turns a coarse, uneven structure into a uniform, fine-grained one.
- 05 Quenching and Tempering Quenching and tempering: hardening followed by high-temperature tempering for high strength and toughness in steels such as 42CrMo4 and C45.
