SUPERHARD Hardfacing 650 2Kg Pkt

Features and Benefits: WELDarc Superhard 650 Hardfacing Electrodes are resistant to impact, compression and abrasion Rutile-basic coated general purpose hardfacing electrode for applications subject to impact, compresion and abrasion wear, for hard facing componets of carbon steel, cast steel and manganese steel. The weld deposit is tough, hard and crack resistant. Applications: Crusher Jaws Wheel Rims Rollers Bulldozer Tracks Plough Shares Block Presses Running Surfaces Cutting Edges...etc Welding Procedure: Due to lower dilution, DC straight polarity will produce a higher first pass hardness and is also ideal for thin sections. Remove all damaged or fatigued metal. Preheating is generally not required. However, for high carbon Low alloyed steels, tool steels and cast iron, a preheat of approximately (200>400°C) is recommended depending on thickness and composition of material. Maintain a short arc using a weave technique. Remove slag. Slowly cool in still air after surfacing. Hardness: 58>60 RC Obtained in pure weld metal Recommended Current: -DC+DC or AC Weld Deposit Properties: Hardness as Deposited/58-60 RC Deposit Thickness/2-3 Passes Deposits are non-machinable Grind Only
