Heat Treatment & Finishing

All steel castings require heat treatment to achieve the correct metallurgical properties prior to shipment.

The heat treatment processes available inhouse are:

⦁    Normalising of Steel
⦁    Annealing of Steels
⦁    Stress Relief Annealing of Irons and Steels
⦁    Quench and Tempering of Steels
⦁    Solution Annealing of Stainless Steels
⦁    Precipitation hardening of Stainless Steels
 

Austral Alloys has four electric heat treatment furnaces all of which provide calibrated temperature control and continuous data logging. All furnaces are controlled & monitored by Shimaden Microscan wireless technology allowing them to be accessed remotely via laptop and are accompanied by water or air blast quenching facilities.
