Hobart 54JK70 MIG Welding Wire Stainless Steel 10 lb

Hobart 54JK70 Stainless MIG Wire

This 10 lb spool of Hobart 54JK70 MIG welding wire is formulated for stainless-steel fabrication. It targets professional welders and serious hobbyists who join grades such as 304, 304L, 308, 308L, 321 and 347 using a MIG (GMAW) process with DCEP polarity.

Sustained welding performance

The wire carries AWS classification ER308/ER308L and delivers 85 ksi tensile strength with 59 ksi yield strength as welded. These mechanical values hold across long production runs, so bead integrity remains consistent when heat input builds up on thicker stainless sections.

Compatibility checks before ordering

Verify that your wire feeder accepts a 0.03 in diameter on a plastic spool and that your power source is set for DCEP output. Confirm the base metal grade matches the listed 201, 202, 301, 302, 304, 304L, 304LN, 308, 308L, 321 or 347 series. Note the California Proposition 65 warning for cancer and reproductive harm.
