PRODUCT DESCRIPTION:
The Lincoln Electric LCN-ED032888 ROD EX 9018-B3MR H4R 1/8″ is a premium Excalibur® low-hydrogen stick welding electrode tailored for welding low-alloy steels such as 2.25% chromium / 1% molybdenum grades used in heavy industrial applications like pressure vessels, power plants, petrochemical process piping, and structural components. Classified AWS E9018-B3 H4R, this electrode delivers a smooth, stable arc with reliable slag removal and excellent mechanical properties, including high tensile and yield strength after stress relieving. Designed for use on both AC and DC+ machines and in all common welding positions (except vertical down), it’s supplied in a sealed 50 lb can for moisture protection and consistent performance.
