Medium-alloy tubular cored electrode of basic type designed for tough and wear resistant hard facing deposits on parts subjected to heavy wear. Weld metal is though and free from cracks and therefore resistant to shock and impact. Machining is only feasibly by grinding. A buffer layer with AMA FC31 is only required in case of difficult-to-weld base metal.
