The material 1.4980 is a high-temperature steel. In the anneale condition, the structure austenite an carbides on. In the cured state, the structure is austenitic steels, carbides and intermetallic phases. Shal due the cure hardness and strength increases. This steel can be up to a maximum temperature of about 700 °C / 1292 °F aare used. Typical products from 1.4980 are, for example, connecting parts, wich are used in turbine construction.
