CROMOTHERME-9M
AWS: SFA 5.5 E8018-B8
EN ISO CODE:
Cromotherme-9M is a basic coated, low hydrogen electrode for depositing 9Cr - 1Mo weld metal. The weld metal is resistant to oxidizing atmospheres up to about o 700 C. It is used for welding similar composition plates, pipes, forging and tubes where sub zero impact properties are required. Typical applications include welding of A387 Gr.9 plate, A335 P9 pipe, A217 C12 castings, A213 T9 tubes, etc.
