Hard Facing Electrodes - Hardmangan |
Characteristics :
A medium heavy coated, low hydrogen type hardfacing electrode. It gives 11-14% austenitic manganese steel weld deposit which work hardens in service from 200 BHN to 500 BHN. It has excellent resistance to wear by impact. Recommended for abrasion resistant hardfacing of Manganese Steel, Cast & Mild Steel. |
Applications :
Filling up worn out parts such as Rock Crushing Jaws, Dredger Bucket Teeth, Rail Crossovers, Cement Grinder Rings, Austenitic Manganese Steel Castings, Muller Tyres, Manganese Steel Rails, various parts of Earth moving equipments.
