STEIN 耐磨焊丝 MF A861M EN ISO 14700: T Fe8 WELDING POSITIONS: FEATURES BENEFITS APPLICATIONS ? Superior hardness as a result of special ? Well suited for wear resisting parts subject to ? Automatic and mechanized welding carbides heavy impact and shock, as well as abrasion ? Bucket and loader teeth ? Good reignition characteristics ? Surface remains free of cracks ? Conveyors ? Virtually no slag coverage ? No re-drying ? Crusher jaws and cones ? Smooth arc characteristic ? Suitable for robot applications ? Weld metal machinable only by grinding ? Welding without shielding gas possible ? A buffer layer is recommended for critical materials or multi-layer build up WIRE TYPE Gas shielded metal-cored wire SHIELDING GAS 75-85% Argon (Ar)/Balance Carbon Dioxide (CO2); Welding without shielding gas possible Gas !ow 12-18 l/min TYPE OF CURRENT Direct Current Electrode Positive (DCEP) STANDARD DIAMETERS ? 1.6 mm (1/16?) RE-DRYING Not required due to seamless wire design STORAGE The same conditions as for solid wire. Product should be stored in a dry, enclosed environment, in its original undamaged packaging WELD METAL ANALYSIS (%) (typical values for mixed gas 82% Ar / 18% CO2 ) Carbon (C) 1.3 Nickel (Ni) - Manganese (Mn) 0.8 Molybdenum (Mo) - Silicon (Si) 1.4 Chromium (Cr) 6.5 Niobium (Nb) 6.5 HARDNESS OF PURE WELD METAL FROM THE 3rd LAYER (typical values for mixed gas 82% Ar / 18% CO2 ) Hardness Rockwell (HRC) 56 - 64 The achieved hardness as well as the structure of the hardfacing depends on (among others): Base material, welding parameters, working and interpass temperature, heating up, cooling down, number of layers, hardfacing methods and shape of component Hurdle Welding 200120 Shanghai Tel: +86 (21) 20967692 Fax: +86 (21)51062692 www.hurdle-tech.com Date:2015-06-12
