Quenching and tempering

Hardening and tempering at higher temperatures for specified strengths with the highest possible toughness.

Annealing

Annealing is the generic term for various heat treatment processes such as normalising, soft annealing or stress relieving.

Straightening

Bar steel and tubes are straightened according to customer specifications to meet the straightness tolerances for further processing.
