CLASSIFICATIONS: E90T1-K2C per AWS A5.29, ASME SFA 5.29
Select 91-K2 is a low alloy steel, gas-shielded, flux cored wire intended for welding
where a 90,000 psi minimum tensile strength is required. This electrode is designed for
single and multiple pass welding of horizontal fillets and flat position weldments of
certain low alloy steels.
APPLICATIONS:Select 91-K2 is well suited for steels such as HY-80, Hy-100, ASTM
A710, A514 and other similar high strength, low alloy steels. Typical welding uses
involve the fabrication of offshore platforms and leg assemblies, earthmoving machinery
and specialized structural applications.
