AWS E330H-16
Descriptions & Applications:
Fully austenitic heat resisting electrode with a rutile coating made on a high alloy core wire designed to weld 18/37 type alloys. Smooth stable arc, low spatter loss, easy releasing slag and smooth porosity free welds. The electrode is designed to match 18/37 type alloy fully austenitic high alloy resisting steels, which will retain a good mechanical strength up to temperatures of 1050°C to 1100°C. Ideal for use in the heat treatment industries and high temperature process plants such as furnace roller – furnace fittings and headers – heat treatment trays and containers – moulds – hearth plates – retorts – radiant tubes.
