Solid Wire Electrode BA-S CrMo5 for Submerged Arc Welding

EN ISO 24598-A: S S CrMo5
SFA 5.23 / AWS A5.23: EB6

Main Application

Submerged arc welding wire suited for high temperature creep resistant 5%Cr0.5%Mo steels. The 5%Cr0.5%Mo creep resistant alloy is used for hot hydrogen service, high temperature strength at service temperatures up to +600°C. Typical applications are found in oil refineries.

Base Materials

5%Cr0.5%Mo creep resisting steels.
X12CrMo5, GX12CrMo5
ASTM: A182/A336 grade F5, A199/A213 grade T5, A217 grade C5, A234 grade WP5, A335 grade P5, A387 grade 5
Suitable flux: WP 380

Flux type suitability is strongly dependent on its application. In combination with the wire electrode the most suitable flux should match the requirements of the plate material as closely as possible under the existing welding conditions. Further information can be obtained from the technical flux data sheets.
