High frequency surface hardening

Maximum part dimensions:

• cylindrically shaped parts with a maximum diameter of 140 mm and maximum hardened surface length of 200 mm
• chain wheels and sprockets with diameter up to 400 mm
• maximum clamping length 600 mm
• maximum part weight 40 kg

Materials:

• 12 050, 12 060, 15 142, 15 240, 12 061

Properties:

• high surface hardness while maintaining ductile core; possible partial hardening

Depth of hardening penetration:

• from 0.7 to 2 mm

The technology is only capable of hardening the part's surface. Heating is provided by an inductor of a corresponding shape (high-frequency alternate current passes through the inductor), followed by water spray or water bath cooling.
