Lincoln Electric Excalibur® 11018M MR® Electrode | 10lb x 14"

Lincoln Electric Excalibur 11018M MR Stick Electrode – ED032607 (50 lb Box)
Low-alloy, low-hydrogen electrode for high-strength welding in demanding structural applications

The Lincoln Electric Excalibur 11018M MR (ED032607) is a premium low-alloy, low-hydrogen stick electrode formulated for critical applications requiring high tensile strength and excellent notch toughness. With a tensile strength rating of 110,000 psi and advanced moisture-resistant coating, this E11018M H4R electrode is ideal for structural steel, high-strength fabrication, and code-compliant work where weld integrity is non-negotiable.

Product Highlights

• High tensile strength: 110 ksi minimum

• AWS classification: E11018M H4R for structural code welding

• Moisture-Resistant (MR) coating reduces risk of hydrogen cracking

• Excellent toughness and impact properties, even in low temperatures

• Suitable for AC or DC+ (DCEP) polarity

• Engineered for superior arc control, low spatter, and easy slag removal

Applications
Excalibur 11018M MR is specifically designed for critical welds in industries such as pressure vessel fabrication, bridge construction, offshore platforms, crane manufacturing, and heavy equipment where high-strength low-alloy steels are used. Its mechanical properties make it an excellent choice for weldments subject to dynamic loading and cold service.

Why Choose Excalibur 11018M MR Over Standard Low-Hydrogen Electrodes
Unlike standard 7018 electrodes, the Excalibur 11018M MR is engineered for high-strength steel applications requiring tensile strength beyond 100 ksi. Lincoln’s proprietary moisture-resistant coating ensures consistent low hydrogen levels, even in field environments with variable storage conditions. The result is fewer weld defects, improved mechanical performance, and increased confidence in structural integrity.
