MK8018B20000930E00 - E8018-B2 1/8" Low Alloy Stick Electrode - 50lb Can

High-Performance Chrome-Moly Welding Electrode

The Exocor E8018-B2 is a premium low-alloy stick electrode specifically engineered for the welding of 1-1/4% Chromium and 1/2% Molybdenum steels. This electrode is a critical consumable in industries requiring materials that can withstand high temperatures and high pressure, such as power generation, petrochemical processing, and heavy industrial manufacturing. The E8018-B2 classification indicates a tensile strength of at least 80,000 psi, making it suitable for structural applications where mechanical integrity is paramount.

One of the defining characteristics of this electrode is its chemical composition, designed to match the base metal properties of Cr-Mo steels often found in boilers, pressure vessels, and high-pressure piping systems (such as ASTM A335 P11). The addition of Chromium and Molybdenum provides excellent creep resistance and strength at elevated service temperatures, ensuring the longevity and safety of the welded components. The electrode features a specially formulated low-hydrogen iron powder coating, which facilitates a smooth, stable arc and minimizes the risk of hydrogen-induced cracking—a critical factor when welding alloyed steels.

This product is supplied in a 50lb hermetically sealed container. This packaging is essential for maintaining the low-hydrogen status of the coating during storage and transport. Moisture absorption in low-hydrogen electrodes can lead to porosity and weld defects; the hermetic seal ensures that the electrodes arrive in factory-fresh condition, ready for critical code work immediately upon opening. The 1/8-inch (3.2mm) diameter is a versatile size, suitable for a wide range of material thicknesses and joint configurations.

Technical Specifications & Compliance

The Exocor E8018-B2 meets AWS A5.5 specifications, ensuring compliance with rigorous industry standards. It is designed to operate on both Direct Current Electrode Positive (DCEP) and Alternating Current (AC), providing flexibility for various power sources. The electrode offers all-position welding capabilities, allowing operators to perform high-quality welds in flat, horizontal, vertical, and overhead positions without compromising bead appearance or mechanical properties.
