EN 10216-2 Grade 11CrMo9-10 quenched and tempered (+QT)
EN 10216-2 Grade 11CrMo9-10 quenched and tempered (+QT) introduction
Seamless tubes of the high-temperature 11CrMo9-10 are used in steam boiler and pipeline construction, pressure vessel and apparatus engineering, especially in chemical industry and power station construction at temperatures from approx. 200 °C to maximum 400 °C and simultaneously high pressures. The total load and the special scaling circumstances can decrease or increase the temperature limit.
Weldability is available.
