EN 10216-2: X10CrMoVNb9-1 Seamless Tube – Normalized & Tempered for High‑Temperature Applications
Seamless tubes of the high-temperature X10CrMoVNb9-1 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.
