Description:
Structural alloy steel for carburizing, with higher strength, thermally processed for obtaining a ferrite-perlite structure. Thanks to the use of chromium, molybdenum and nickel, it has high strength and is suitable for larger elements as well.
Applications:
Heavily-loaded structural elements for cars and high-performance gearboxes, bevel sprockets, gearwheels, shafts, bolts. Heavy-duty high-speed gear units, shafts and other parts subject to high pressures.
