BrandHHBMo(Z) wear resistant welding wire Diameter(mm)2.8 3.2 4.0 The solidity of the welding cladding(HRC) 60-65 special open arc welding wire for hing chromium cast iron synthetic wear-resistant plateHHBMo(Z) features an excellent performance of welding process, a beautiful welding seam and small spraying. Gas or flux conservation is unnecessary during welding so that it simplifies the welding process and saves the costs of welding support materials. Small cracks will appear during surfacing which is the result of the release of stress, therefore it won`t affect the normal use under the low-impact mining conditions. HRC 60-62 Beijing Hanbo Welding Company has developed fine diameter flux-cored self-shield welding pieces applicable in different occasions for 1.2 and 1.6. Specifications: 1.2, 1.6, 2.4 The hardness of the hard wearing welding wire for surfacing HB-YD988(Q) HRC63 is high. After many experiments conducted for the development of HB-YD988 and through improved alloy structure and production process, HB-YD988 has successfully become the first such high-hardness hard wearing welding wire for surfacing (gas shielded welding) in China and its hardness is over HRC63.
