Stainless Steel Welding Electrode E-BK Hard Mn14
E Bk hard Mn14 is a manganese steel coated electrode. It is suitable for multi-layer build-up and has excellent work hardening characteristics. This electrode with a recovery of 140% can be used for joining and overlay on manganese steels that are worn out and need to be rebuilt. Heat input should be below. Good bond on steel, cast steel, and manganese steel. Smooth deposit with very low friction coefficient.
Applications
Hard facing of mining and rock-crushing machine parts as well as of hard manganese steel . austenitic manganese steel, high impact loads, hammers, crushers, rebuilding, hard facing, rails, crossings, Breaker teeth, etc..Classification
