GENERAL CHARACTERISTICS

All position, low hydrogen iron powder type electrode with a fast and efficient metal transfer. Deposits have outstanding elongation and ductility and provide crack free welds under highly stressed conditions. The slag is easily removed from the smooth welds, which are easily machined.

TYPICAL APPLICATIONS:

HPP 164 is designed to weld low alloy high strength steels such as T-1, Hy-80, Hy-90, Hy-100, SSS 100 and Jalloy 90 and 100. Commonly used to fabricate tanks, containers, covers and high strength pipe. Also recommended for welding low alloy steels containing nickel, manganese, molybdenum, and chromium such as I-beams, angle iron, scaffolding, and super-structures. Weldments can be used "as welded" or "stress relieved".

Technical Data:

Tensile Strength as welded..up to 113,000 PSI

Yield Strength..up to 104,000 PSI

Elongation....approx 23%

Procedure: No preheat is necessary when welding low carbon steels. When joining heavy sections to thin sections and when low alloy or higher carbon steels are welded, a preheat of 4000F to 6000F (2000-3000C) is recommended. Maintain a short arc with either stringer or weave beads. Allow deposit to cool normally before chipping off slag. To stress relieve, heat to 10250F (5500C) and maintain for 1 hour.
