Welding of Ferritic Creep-resistant Steels - TWI

The creep resistant steels all contain strong carbide and/or nitride forming elements.These are intended to provide a fine dispersion of precipitates that both increase the tensile strength and impede the formation of the voids illustrated in Fig 1 and Fig 2 of Job Knowledge No.81.Chromium is also added to reduce the scaling or oxidation of the steel at high temperatures.Thermal History and Mechanical Properties in Grade 91 SteelThe improved high-temperature strength and creep resistance of the parent steel over predecessor alloys,eg 12CrMoV CREEP RESISTING STEEL#189;Cr 12CrMoV CREEP RESISTING STEEL#189;Mo 12CrMoV CREEP RESISTING STEEL#188;V,1CrMo,2 12CrMoV CREEP RESISTING STEEL#188;Cr1Mo and 12CrMoV (X20) grades,has helped to reduce thicknesses and thus minimise stresses due to thermal cycling.Strengthening of a 12CrMoV turbine blade steel by Commercially available martensitic 12CrMo,12CrMoV,and HCrMoVNb steels in the tempered condi-tion are often used to fabricate turbine blades.Tempering,done at the processing stage itself,is usually carried out at a temperature approximately 100 to 150 12CrMoV CREEP RESISTING STEEL#176; above the service temperature.At the service temperature,the steel und 12CrMoV CREEP RESISTING STEEL#232;rgoes a second tempering.
