CLASSIFICATIONS: E91T-GM per AWS A5.29

This all position, low alloy, flux cored electrode is designed to weld low alloy steels where a minimum tensile strength of 90,000 psi is required.

APPLICATIONS: When good low temperature toughness and a minimum tensile strength of 90,000 psi are needed, Select 937Ni represents an outstanding choice. Lack of fusion is not a problem due to this wire’s deep penetrating characteristics. Typical applications include offshore structures, earthmoving machinery and other specialized structural uses requiring good low temperature toughness.

DIAMETERS:
