Field Hose Welding Technology for High Manganese Steel Slurry Pipelines

摘要

The present invention relates to a welding composition for bonding high manganese steel base metal and a method of applying the same. Wherein the composition comprises carbon from about 0.4% to about 0.8% by weight; Manganese ranging from about 18% to about 24% by weight; Chromium in an amount up to about 6 percent by weight; About 4% by weight or less of molybdenum; Nickel in an amount up to about 5 percent by weight; From about 0.4% to about 1.0% silicon by weight; A quantity of sulfur less than about 200 ppm; An amount of less than about 200 ppm phosphorus; And a remainder comprising iron. In one embodiment, the composition has an austenite phase.
