EN 10216-2 Grade X11CrMo5 +I,isothermic annealed
EN 10216-2 Grade X11CrMo5 +I,isothermic annealed introduction
Seamless steel tube for pressure purposes with specified elevated temperature properties.
The steel grade meet the essential requirements of Directive 97/23/EC.,Seamless tubes of the high-temperature X11CrMo+I 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.,Seamless tubes of the high-temperature X11CrMo+I are used in steam boiler and pipeline construction, pressure vessel and apparatus engineering, especially in chemical industry and power station construction at temperatures up to approx. 550 °C and simultaneously high pressures. The total load and the special scaling circumstances can decrease or increase the temperature limit.
When welding it should be considered that the behavior of the steel depends during and after welding on the applied heat treatment, the preparation and execution of the welding.
