Quality UP-EB8
Classification DIN EN ISO 24598-A-S S CrMo9
Material No. -
Classification AWS A5.23 EB8
Approvals -
Characteristics and application UP-EB8 is a submerged arc welding wire for high temperature creep resistant 9%Cr-1%Mo ferritic steel, i.e. P9.
The 9%Cr-1%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 9%Cr-1%Mo creep resisting ferritic steels.
