Heat treatment is a controlled process used to alter the microstructure of metals and alloys to impart properties which benefit the working life of a component, for example increased surface hardness, temperature resistance, ductility and strength. Heat treating can soften metal, to improve formability. It can make parts harder, to improve strength. It can put a hard surface on relatively soft components, to increase abrasion resistance. It can create a corrosion-resistant skin, to protect parts that would otherwise corrode. And, it can toughen brittle products.
We KNDT ARABIA Co.Ltd have established facilities for heat treatment using electrical resistance method with well trained personnel to operate. Our services include, Pre-heat, Post heating, Stress relieving, Annealing, Normalizing, Solution annealing, tempering and step cooling.
The power sources are 380/415/440V 3 phase 50Hz primary supply step down transformer secondary output (heat treatment unit) giving low voltage circuits. Temperature control equipment is either manually operated through regulators or automatically operated using program modules. Recording of temperature, for the electrical resistance method, or the induction heating method is by means of chart type temperature recorder.
