MK8018B220001250E0 - E8018-B2 3/16" Chrome-Moly Stick Electrode (50lb Can)

High-Performance Chrome-Moly Welding Electrode

The Exocor E8018-B2 is a premium quality, basic-coated, low-hydrogen electrode designed specifically for the welding of low-alloy creep-resistant steels. Engineered with a nominal composition of 1.25% Chromium and 0.5% Molybdenum, this electrode is the industry standard for joining materials that must withstand high temperatures and high pressure over extended periods. It is meticulously manufactured to meet the rigorous AWS A5.5 specifications, ensuring consistent mechanical properties and chemical composition essential for critical infrastructure projects.

This electrode excels in applications involving power generation and petrochemical processing where materials such as ASTM A335 Grade P11 or A387 Grade 11 are utilized. The E8018-B2 formulation provides excellent creep rupture strength and ductility, making it indispensable for fabricating boilers, pressure vessels, and high-pressure piping systems. The controlled chemical composition ensures that the weld metal maintains its integrity and strength even when subjected to prolonged elevated temperatures, reducing the risk of structural failure in demanding environments.

One of the standout features of this product is its hermetically sealed packaging. Low-hydrogen electrodes are highly susceptible to moisture absorption from the atmosphere, which can lead to hydrogen-induced cracking and porosity in the weld. The 50lb hermetically sealed can guarantees that the electrodes remain factory-dry and ready for immediate use, eliminating the need for pre-baking in many scenarios and ensuring the lowest possible diffusible hydrogen levels. This attention to packaging integrity reflects the product's suitability for code-quality work where X-ray quality welds are mandatory.

The coating is formulated to provide a stable arc and easy slag removal, although the primary focus of the Josef Gas technical assessment is on the metallurgical superiority. The slag system is designed to support out-of-position welding, although 3/16" diameter rods are typically used in flat and horizontal positions for fill and cap passes on thick-walled pipe and plate. The resulting weld deposit exhibits high tensile strength (minimum 80,000 psi) and reliable impact toughness.
