Kobelco - Electrode - E9018-B3

Kobelco CM-B108 is a high-performance, basic-coated low-hydrogen stick electrode within Kobelco's elite TRUSTARC series.
It conforms strictly to the AWS A5.5 E9018-B3 international industry classification.

Key Specifications & Applications
Target Materials: Specifically engineered for welding high-strength, low-alloy creep-resisting steels.
It is the benchmark choice for joining ASTM A387 Grade 22 plates, A335 Grade P22 piping systems, and A213 Grade T22 boiler elements.
Chemical Profile: The deposited weld metal contains 2.25% Chromium (Cr) and 1% Molybdenum (Mo). This chemistry ensures exceptional structural integrity, resistance to high-temperature hydrogen attack, and creep deformation resistance.
The "18" Coating Advantage: Features an iron-powder basic flux coating. This design maximizes deposition efficiency, provides excellent arc stability, and allows for all-position welding performance (except vertical-down).
Welding Parameters: Deployed via Shielded Metal Arc Welding (SMAW / Stick), operating smoothly on both Alternating Current (AC) and Direct Current Electrode Positive (DCEP) polarities.
Identification: Kobelco brands these electrodes with a distinct double-color band system featuring a 1st Black and 2nd Pink identification mark on the tip.
Common Use Cases: Widely deployed across heavy industrial boiler fabrications, oil refinery processing vessels, chemical reactors, and high-pressure power plant steam lines operating at elevated service temperatures up to 600°C.
