Description
AWS ER80S-G solid welding wire is a kind of high tensile strengh welding wire, also called mag/mig welding wire which is matched with CO2 gas or Arc gas in welding. It has strong resistance to surface scales and oil stains on the base metal. It has low blowhole sensitivity.
Application: Suitable for structures fabricated by 1.25Cr-0.5Mo-0.25V series pearlistic heat resisting low alloy steels, such as heavy equipments of thermal powder stations and nuclear powder stations, petroleum & chemical industries which work temperature between 510º C to 550º C. Preheating temperature and interpass temperature should between 180º C to 300º C and the welded piece should be tempered at 710º C -730º C not shorter than 2 hours after welding.
Packing: 5kg/10kg/15kg/20kg/spool in carton, 250kg/ drum, 21.6MT -25.2MT per 1X20" FCL.
