ER80S-B6
Alloy Type: A5.28, LOW-ALLOY STEEL Filler Metals for Gas Shielded Arc Welding
ER80S-B6 is designed for welding of materials of similar composition, especially those for high temperature service conditions. This alloy is an air-hardening material and as such calls for preheat and interpass temperatures of 350 degrees F minimum during welding. This alloy is resistant to oxidation, heat, corrosion and wear.
Typical Applications: boilers, steam boilers, pressure tanks, oil industry, thermo electrical industry, chemical and petroleum industry
