8018-B2 is Cr-Mo covered electrodes commonly used in maintenance and fabrication of 1/2 % Mo and 1/2 -1.25 % Cr where base metals in the power / boiler piping and equipment may be found. 8018-B2 can be used for base metal such as A335-P2, P11, P12, A119-T11, A301-B, A217-WC6, and A182-F11. The low hydrogen potassium, iron powder covering has high deposition with good smooth arc, low spatter and easy slag removal. Preheat of 300-500° F and postheat of 1250-1350°F are often found with this alloy.
