Electrodes for Creep Resisting Steels

CROMOTHERME-9L

AWS: SFA 5.5 E8018-B8L EN ISO CODE: 3580-A E CrMo9 B 4 2 H5

A low hydrogen type electrode specially designed for welding of ferriticmartensitic chrome steels. The weld deposit contains low carbon 9Cr - 1Mo air hardanable weld metal calls for suitable preheat and post weld heat treatment. Weld deposits are of radiographic quality. Typical applications include welding of A387 Gr.9 plate, A335 P9 pipe, A217 C12 castings, A213 T9 tubes, etc.

Precaution

1. Ensure the electrodes are dry. Re-dry the electrodes at 250-300 C for one hour.

2. Use short arc, low current and stringer beads.
