Blue plastic spool with 33 lb of 0.035 in low-alloy steel MIG welding wire

Westward

Westward 20AP74 MIG Welding Wire 0.035" 33 lb

SKU CH-RWGE-4MPFE

33 lb spool of 0.035 in low-alloy steel MIG wire rated at 80 ksi tensile and 68 ksi yield for ASTM-grade steel

  • Low-alloy steel wire joins matching ASTM-grade steels
  • ER80S-D2 classification meets 80 ksi tensile strength
  • 68 ksi minimum yield strength supports structural loads
  • 035 in diameter suits standard MIG guns
  • 33 lb plastic spool feeds smoothly in GMAW process

Purpose & Audience

Westward 20AP74 MIG welding wire is a 33 lb spool of 0.035 in diameter ER80S-D2 low-alloy steel filler metal. It is designed for fabricators and maintenance welders joining low-alloy steel grades such as ASTM A182, A217, A234, A335 and A336 using the GMAW process with DCEP polarity.

Upgrade Context

The wire replaces lower-strength mild-steel fillers when the joint requires a minimum 80 ksi tensile strength and 68 ksi yield strength as welded. The jump is worth it when the base material specification demands the higher mechanical properties listed for these ASTM grades.

Compatibility Check

Verify that your wire feeder accepts plastic spools and can handle 0.035 in diameter wire. Confirm the power source is set for DCEP output and that the shielding gas mix is appropriate for ER80S-D2 low-alloy steel welding. Check local regulations regarding the Proposition 65 warning for this product.
