Medium and High Tensile Steel

A basic coated low hydrogen iron powder type electrode for welding high tensile steels. The weld metal is of radiographic quality. Ideally suited for welding high tensile steels, Q&T steels, castings, etc. with UTS range of 71 kgf/mm². The weld metal possesses high strength combined with excellent toughness at sub-zero temperatures.

1. Ensure the electrodes are dry. Re-dry the electrodes at 300°C for 2 hours.

2. When welding grain refined and Q&T steels, control the heat input by using:

(a) Stringer bead. (b) Control over preheat and interpass temperature. (c) Short arc.
