This group is composed by the construction steels suitable for the manufacturing of components that have to be subjected to the creep phenomenon, for the combined action of temperature + stress + time and therefore used in thermal plant.

The steel with 5% of Chrome and 5% of Molybdenum (our C5K6) has a good resistance up to the temperature of 600° C, furthermore it resists to the oxidation and to the intercrystalline corrosion satisfying the requirements of the creep.
