CROMOTHERME-9L(MOD); AWS: SFA 5.5 E8018-B8L; Electrodes for Creep Resisting Steels


Description

A low hydrogen type electrode specially designed for welding of ferritic- martensitic chrome steels. The weld deposit contains low carbon, low sulphur, low phosphorous, 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.
