What we do
Hardening and tempering (atmosphere/vacuum)
Case hardening is the process of hardening the surface of a metal by infusing elements into the material’s surface, forming a thin layer of harder alloy.
Combined with a subsequent hardening operation the desired component properties can be varied to suit the application.
Our Hardening (quench & temper) services
Neutral hardening
A heat treatment used to achieve high hardness/strength on steel which consists of austenitising, quenching and tempering, in order to retain a tempered martensite or bainite structure.
Press quenching
The controlled hardening in restraining dies of close tolerance components, such as gears. Ensures good dimensional control and uniform hardening.
Induction hardening
Case hardening process that increases wear resistance, surface hardness and fatigue life via a hardened surface layer while maintaining an unaffected core microstructure.
Double hardening
A treatment in which a part is subjected to two complete hardening operations, or first an annealing process followed by a hardening process.
Our Austemper & marquench services
Ausbay quenching
Quenching technique that reduces the residual internal stresses and distortion resulting from non-uniform transformation and thermal shock typical of conventional oil quenching.
Austempering
Heat treating process for medium to high carbon ferrous metals producing a metallurgical structure called bainite, used for strength, toughness, and reduced distortion.
Martempering/Marquenching
Interrupted quenching of steels, at a temperature just above the martensitic phase. Delayed cooling equalises temperature and minimises distortion, cracking and residual stress.
