MK8018B20001560E0 - Exocor E8018-B2 1/8" Chrome-Moly Stick Electrode

Premium Chrome-Moly Welding Electrodes for High-Temperature Applications

The Exocor E8018-B2 1/8" Electrode is a high-performance stick electrode designed specifically for the welding of low alloy steels containing 1.25% Chromium and 0.50% Molybdenum. This specific alloy composition is engineered to provide exceptional creep resistance and high tensile strength in environments subjected to elevated temperatures and high pressures. It is the preferred choice for industrial fabrication involving materials such as ASTM A335 Grade P11 and A387 Grade 11, commonly found in power generation and petrochemical sectors.

Manufactured with a basic, low-hydrogen coating, this electrode significantly reduces the risk of hydrogen-induced cracking, a critical factor when welding alloyed steels. The coating is moisture-resistant, though proper storage and handling practices—such as using rod ovens—are recommended to maintain its low-hydrogen status. The Exocor E8018-B2 delivers X-ray quality welds, ensuring that critical joints in pressure vessels and piping systems meet stringent code requirements.

At Josef Gas, we understand the rigorous demands of industrial maintenance and fabrication. This electrode offers stable arc characteristics and can be used in all positions, providing versatility for on-site repairs and complex pipe assemblies. Whether you are welding boiler tubes, heat exchangers, or high-pressure steam pipes, the Exocor E8018-B2 ensures a durable, defect-free bond that stands up to the harshest service conditions.

Key Technical Considerations:

• Base Metal Matching: Specifically formulated for 1-1/4 Cr - 1/2 Mo steels.
• Heat Treatment: Welds typically require preheat and post-weld heat treatment (PWHT) to relieve stresses and achieve optimal mechanical properties.
• Storage: Keep in a dry environment; re-bake according to manufacturer specifications if exposed to moisture.
