MH Z208 is a cast iron electrode with low carbon steel core and strong graphitization coating. If beamis slowly cooled, it may turn into gray cast iron with poor crack resistance. AC/DC both can be suitable to use the cast iron tig rod.
Weldability: MH Z208 cast iron electrode has excellent weldability and can adapt to the needs of different welding conditions. When welding, the electrode can quickly melt and form a uniform weld, and the welding joint is strong and reliable.
Low temperature toughness: MH Z208 cast iron electrode maintains good toughness under low temperature conditions, which can effectively prevent the phenomenon of cold and brittle fracture of welded cast iron.
Strong wear resistance: MH Z208 welding rod after the cast iron surface hardness is high, strong wear resistance. Welded joints can withstand certain friction and wear and have a long service life.
