100 Blue Lightning Tough Duplex Alloy 1/8

Blue Lightning is a tough duplex alloy designed for dissimilar welding applications of ferrous metals (except cast iron).
• AC Welding — special flux coating enhances operability on buzz boxes and DC inverter welders
• High strength — resistant to heat and corrosion, but still machinable
• High elongation — tough welds stand up to impact and shock
• Versatile — welds steel, stainless steel, manganese steel, HY steels, alloy steels, tool steels and nickel alloys to steel and dissimilar combinations of these alloys
• All-position welding and easy slag removal
• Tensile strength:– as deposited: 95,000 psi/655 MPa– work hardened: up to 130,000 psi/896 MPa
• Hardness:– as deposited: 93 Rb– work hardened: up to 35 Rc
• Elongation: 30%
• Machinability: Excellent
• Heat resistance: Good
• Corrosion resistance: Good
• Current: DCEP (DC+) or AC
Remove defective metal by grinding or gouging with Arc-Prep #161 electrode. Bevel heavy sections before welding. Use AC or DCEP (DC+) current. Use a contact or a minimum arc length with a weave or stringer bead technique. Preheat should be used when the base metal requires it. For vertical-up welds reduce amperage slightly and use a modified weave technique. Chip the slag between multipass welds. Allow to cool slowly.
