FIELD CIRCUMFER WELDING TECHNOLOGY FOR HIGH CONTENT MANGANESE FLUID STEEL PIPES

摘要

The present disclosure relates to a welding composition for joining high manganese steel base metals and methods of applying it. The composition includes: carbon in a range from about 0.4 wt% to about 0.8 wt%; manganese in a range from about 18 wt% to about 24 wt%; chromium in an amount of about 6% by weight; molybdenum in an amount of = about 4% by weight; nickel in an amount of = about 5% by weight; silicon in an amount from about 0.4 wt% to about 1.0 wt%; sulfur in an amount of = about 200 ppm; phosphorus in an amount of = about 200 ppm; and a balance including iron. In one embodiment, the composition has an austenitic phase.
