ED-ER80S-B8
MIG (GMAW) wires for creep resisting steels

Classification DIN EN ISO

21952-A G CrMo9

Material No.

-

Classification AWS

A5.28 ER80S-B8

Approvals

CE

Characteristics and application

MIG/GMAW wire for high temperature creep resistant 9%Cr-1%Mo martensitic steels, 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.
