What We Offer


We oil harden in computer controlled sealed-quench furnaces. Both the austenitising and the quenching processes are carried out in a controlled atmosphere to prevent oxidation or de-carburization.

The hardening process makes steel hard and tough. In this process, steel is heated 30° – 40°C above the upper critical temperature and then cooled to room temperature by quenching in water or oil.

The steel is heated above its critical temperature range then held at that temperature for a definite period of time. The steel is then rapidly cooled in a quenching medium. The quenching medium is selected according to the degree of hardness desired. Examples of quenching mediums are air, water, brine and oils.

  • To achieve the required mechanical properties of steels for different specifications.

Maximum Sizes & Capacity

Our maximum furnace dimensions are broken down into two types:- 


Type A (maximum width furnace):

  • Widest - 880 mm 

  • Highest - 460 mm

  • Length - 1,000 mm


Type B (maximum height furnace):

  • Widest - 860mm 

  • Highest - 650 mm

  • Length - 1,000 mm


Distortion can be minimized up to 650 mm as these items can be stood upright in a Type B furnace. Items of up to 1,000 mm can be laid down flat and packed to minimize distortion, but no guarantee can be given on these items.


Maximum weight is consistent for a Type A and Type B furnace: 250 KG - 800 KG

Allow 48 hours, however extraordinarily large jobs may take longer.


Urgent work is subject to load size and discussion with our Customer Liasion Department.
