Heat Treatment

As a tool steel supplier who also provides heat treatment, ASSAB is both a pioneer and an industry leader. Our heat treatment service helps harness every steel piece for enhanced tool performance.

At ASSAB, heat treatment is meted out with care and precision to attain the required hardness. But more than that, the treatment fortifies high wear and cracking/chipping resistance (for use in blanking and forging); high heat checking and erosion/corrosion resistance, as well as toughness (for die casting) and high corrosion, high polishability and high dimensional stability (for plastic injection moulding).

ASSAB’s premium heat treatment service is possible with its state-of-the-art vacuum furnaces which offer menu-guided process control with full documentation of all process parameters. Heating with hot gas circulator and a cooling pressure of up to 15 bar with nitrogen allows increased heating and cooling performance, as well as furnace temperature uniformity.

Heat treatment in ASSAB is multi-faceted.

 

Hardening and Tempering

To produce the most durable parts with clean surface and minimum distortion.

Stress Relieving

To release the stresses induced by rough machining, welding, electric discharge machining (EDM), or accumulated during the extended service, especially by die casting.

Subzero Processing

To enhance wear resistance and minimise the amount of retained austenite to ensure that tools are highly stable during the service period.

In addition to technical know-how, our team of senior engineers employs the latest test and measuring equipment to provide quality inspection reports of international standard in heat treatment analysis and trouble shooting.
