VL40FO
Average hardenability steel that achieves average hardness, strength and toughness after treatment. Used in the manufacture of medium-sized parts that require average mechanical strength, for oil exploration, capital goods and steelmaking industries.
VM40FO
High hardenability steel that achieves average hardness after treatment. Used in manufacturing larger parts of general use, requiring high hardness and/or mechanical strength, particularly for steel, mining and oil exploration industries.
VM50FO
High hardenability steel that achieves increased hardness after treatment. Used in the manufacture of large diameter bearings and gears requiring higher hardness and/or mechanical strength.
VT45FO
Low hardenability and toughness steel that achieves average mechanical strength after treatment. Used in manufacturing large parts that require good mechanical strength and weldability, typically sugarcane milling shafts, power generation shafts, crusher shafts, rods for presses and propeller shafts for ships.
