UP-P24 (S1CrMo2V)

SAW (submerged arc welding) wires for creep resisting steel

Quality UP-P24 (S1CrMo2V)
Classification DIN EN ISO 24598-A-S S Z CrMo2VNb
Material No. -
Classification AWS A5.23 EB24
Approvals TÜV 03274, CE
Characteristics and application Submerged arc welding wire for T24 creep resistant steel. The T24 alloy is a modified 2.25%Cr-1%Mo alloy with additions of Nb and V to improve high temperature creep performance. The alloy finds use for waterwalls in ultra-super-critical (USC) boilers in the power generating industry.
Base materials For matching alloy 24, 2.25%Cr-1%Mo modified, creep resisting ferritic steels.
