Heat treatment

We offer various types of heat treatment of castings, welded structures, road wheels and other details weighing up to 10 Mg / pc. and a total weight of 5 - 30 Mg, which we produce in computer-controlled furnaces, quenching tanks and on a sorbitization rotator. We select the type of heat treatment to the required strength properties.
