Fe-05 high-carbon high-chromium alloy electrode 
 Meet Q/HHJ02-2003 Purpose: The electrode can be surfacing in the low, medium carbon steel, low alloy steel (such as A3, Mn13, 16Mn, 65Mn), may in some gray cast iron used to widely used coal, chemicals, building materials and machinery industry, brick making machine cutter knife, play clay tablets and other wear parts on the manufacture and repair. Single-channel surfacing layer hardness: HRC ≥ 60 overlay chemical composition (%) C Si Mn Cr B other 1.5-2 2-3 1-4 12-15 3-4 ≤ 2 technology: a manual arc welding, DC anti- Next, AC and DC. Welding current: AC :170-200A, DC :160-180A, the dilution rate of surfacing ≤ 50%. Fe-05 Ⅱ type electrode meet Q/HHJ02-2003 Purpose: The electrode can be AC and DC, deposited metal with high hardness and wear resistance, excellent crack resistance can be brick, tile, cement, glass , ceramics and other industries affected by the impact hammer and various parts of the welding repair. Surfacing layer hardness: HRC55 ~ 58, processes: manual metal arc welding, AC and DC. Surfacing layer chemical composition (%) C Mo Cr Mn other 1.5-2.0 0.5-0.9 15-18 0.15-0.3 ≤ 1.0 Fe-05 Ⅲ type electrode of the electrode is consistent with Q/HHJ02-2003 low hydrogen sodium type of Cr-Mo V-type electrode, A & M mixing organizations, under the hard and tough welded excellent crack resistance, the use of DC reverse, is mainly used for welding by the severe impact of wear parts. And has impact resistance, heat resistance, wear resistance. By sand abrasion and cavitation of the water damage to machinery, dredging bucket, rubber and plastic machinery, mining machinery spare parts, weld overlay, no crack. Surfacing layer hardness: HRC50 ~ 55. Surfacing layer chemical composition (%) C Cr Mo V other 0.30-0.60 8.00-10.00 ≤ 3.00 0.50-1.00 ≤ 4.00 reference current: (for type II, III type electrode) electrode diameter of 2.5mm 3.2mm 4.0mm 5.0mm welding Current 60 ~ 80 (A) 90 ~ 110 (A) 140 ~ 180 (A) 180 ~ 220 (A) Notes: 1. before welding electrode to be roasted by the 330 ~ 350 ℃ 1 hour 2. large parts before surfacing properly preheated to about 300 ℃, and welding parts of the surface cleaned of impurities
