CLASSIFICATIONS: E90T1-D3C per AWS A5.29, ASME SFA 5.29
Select 91-D3 is a gas-shielded, low alloy steel electrode intended
to match the mechanical properties and corrosion resistance of certain
pressure vessel steels. This electrode can be used for single and
multiple pass welding in horizontal fillets and the flat position.
APPLICATIONS: Select 91-D3 is a manganese-molybdenum flux
cored electrode which is well suited to weld steels such as ASTM
A302 GrB and manganese-molybdenum castings such as ASTM A49, A291
and A735.
DIAMETERS: 5/64", 3/32"
SHIELDING GAS: 100% CO2, 35-50 cfh
WELDING POSITIONS: Flat and Horizontal
CHARACTERISTICS:
| |
Good welder appeal and excellent bead profile. |
| |
Low spatter levels. |
| |
High strength and corrosion resistance of deposit matches the appropriate steels. |
