HEKO Case Hardening means:
| HEKO chains distinguish themselves through:|
- high quality heat treatment tailored to particular applications
- high fatigue strength
- close length tolerance of chain pairs
Modern welding machines are employed for the manufacture of HEKO chains. Chains are manufactured form a wide range of materials including manganese steels, chrome-nickel steels and fine grain chrome-nickel alloy steels.
Our own, modern, computer-controlled heat treatment processes produce tempered or case hardened chains.
- High breaking load resulting from a tough, fine grain core
- High wear resistant resulting from a surface hardness of min. 800 HV
Case hardening results in a hard, wear resistant chain surface.
HEKO offers 6 hardening depths as standard. In addition HEKO offers various hardening depths to suit individual requirements. A surface hardness of at least 800 HV is supplied as standard.
HEKO tempering means:
- Very high breaking loads
For applications where a high breaking load is taking precedence over hardness, tempered round link chains manufactured from manganese steel, or CrNi or CrNiMo alloy steel are recommended.
