UP-99 CrMo5 (S1CrMo5)

SAW (submerged arc welding) wires for creep resisting steel

Quality UP-99 CrMo 5 (S1CrMo5)
Classification DIN EN ISO 24598-A-S S CrMo5
Material No. 1.7374
Classification AWS A5.23 EB6
Approvals TÜV 03274.06, CE
Characteristics and application Submerged arc welding wire for high temperature creep resistant 5%Cr-0.5%Mo ferritic steel. The 5%Cr-0.5%Mo creep resistant alloy is used for service up to ~600°C particularly in environments involving hot hydrogen gas. Typical applications are found in oil refineries.
Base materials For matching 5%Cr-0.5%Mo creep resisting ferritic steels.
