MK8018B20001560E00 - Exocor E8018-B2 5/32" Stick Electrode - 50lb Hermetically Sealed Can

High-Performance Chrome-Moly Welding Electrode

The Exocor E8018-B2 is a premium quality low-hydrogen stick electrode designed specifically for the welding of low alloy steels containing 1.25% Chromium and 0.5% Molybdenum. Engineered to meet the rigorous demands of the power generation and petrochemical industries, this electrode provides exceptional mechanical properties and creep resistance in high-temperature service environments up to 550°C (1022°F). It is the ideal choice for fabricating and repairing steam boilers, superheater tubes, and pressure vessels where structural integrity under thermal stress is critical.

Metallurgically, the E8018-B2 deposit matches the composition of base metals such as ASTM A387 Grade 11 and A335 Grade P11. The formulation ensures a tough, crack-resistant weld metal that responds well to post-weld heat treatment (PWHT), specifically normalizing and tempering. The electrode features a basic coating that promotes a stable arc and low spatter, while the controlled chemical composition ensures consistent X-ray quality welds. This product is supplied in a 50lb hermetically sealed container, guaranteeing that the low-hydrogen coating remains free from moisture contamination during storage and transport, which is vital for preventing hydrogen-induced cracking in critical applications.

For industrial MRO and fabrication shops, the Exocor E8018-B2 offers reliability and performance. Its all-position capability allows for versatility in complex assemblies, although flat and horizontal positions generally yield the highest deposition rates. Whether used for new construction of heavy-wall pressure vessels or maintenance of high-temperature piping systems, this electrode delivers the professional-grade results required by code-compliant projects.
