ESAB 255055311 8018-B2 5/32 Low-Alloy Stick Electrode 50 lb Hermetically Sealed Can

The ESAB 255055311 is a 5/32-inch diameter 8018-B2 low-alloy steel stick electrode supplied in a 50-pound hermetically sealed can (HSC). Designed for welding creep-resistant chromium-molybdenum (Cr-Mo) steels, this electrode meets the demanding requirements of high-temperature pressure vessel, boiler, and piping fabrication industries.

The 8018-B2 classification indicates a low-hydrogen, iron-powder coating that delivers excellent arc stability, low spatter, and easy slag removal. The 1.25% Cr / 0.5% Mo weld deposit provides superior elevated-temperature strength and resistance to hydrogen attack, making it the go-to choice for power generation, petrochemical, and refinery applications.

Key Features:

• AWS Classification: AWS A5.5 E8018-B2
• Electrode Diameter: 5/32 inch (4.0 mm)
• Package Quantity: 50 lb hermetically sealed can (HSC)
• Coating Type: Low-hydrogen, iron-powder
• Weld Deposit Alloy: 1.25% Cr / 0.5% Mo (Chrome-Moly)
• Tensile Strength: 80,000 psi minimum
• Welding Position: All positions
• Current Type: AC or DCEP (reverse polarity)
• Applications: Pressure vessels, boilers, high-temperature piping, power generation equipment
• Hermetically Sealed Can: Preserves low-hydrogen integrity during storage and transport

ESAB's 8018-B2 electrodes are manufactured to strict AWS A5.5 and ASME SFA-5.5 specifications, ensuring consistent weld quality and compliance with code-critical applications. The hermetically sealed can packaging prevents moisture absorption, eliminating the need for re-drying in most storage conditions and helping maintain the low-diffusible-hydrogen deposit required for crack-free welds in Cr-Mo steels.
