Manganese Chrome
HF 55 Isoarc MC

Descriptions
ISOARC MC is a rutile coated electrode designed for joining and surfacing 11-14% manganese steels. The deposited weld metal will work harden under impact load to a hardness of 480-590 HV. The electrode is recommended for use in the downhand position.

Applications
ISOARC MC can be used to reclaim worn austenitic manganese parts or as a buffer layer on other grades of steels prior to hardfacing. The deposit is extremely crack resistant and will rapidly work harden , making it ideally suited for welding on railway crossings, dredger buckets, crusher jaws, loader buckets, and other ground engaging equipment.
