Value Brand ER309L MIG Welding Wire .045 10 lb

SKU CH-ZC08-7S8ZZ

Stainless-steel MIG wire for joining 304, 308, 309 and similar grades to carbon or low-alloy steel, .045 in diameter on a 10 lb plastic spool

  • TypeWelding Supplies
  • ER309L classification welds dissimilar stainless and carbon steels
  • .045 inch diameter feeds smoothly through MIG guns
  • 10 lb plastic spool supports extended production runs
  • 85 ksi tensile strength delivers reliable joint integrity
  • 58 ksi yield strength meets structural code requirements

Value Brand ER309L 10 lb Spool

This welding wire is supplied on a 10 lb plastic spool and carries AWS ER309L classification. The wire diameter is .045 in and the material is stainless steel. It is intended for MIG welding of stainless steel to carbon steel, low-alloy steel or stainless steel grades such as 304, 308 and 309.

For stainless-to-dissimilar joints.

The filler suits fabricators joining stainless steel to carbon or low-alloy steel and matching 304, 305, 308, 309 or 309S grades. Buyers who need a wire dedicated to a single stainless grade without the higher alloy content of ER309L should look elsewhere.

Tensile strength 85 ksi as welded

The deposited weld metal delivers a tensile strength of 85 ksi and a yield strength of 58 ksi as welded. These mechanical values determine whether the wire meets the design requirements for the intended joint.

Questions about this item

Will the ER309L .045 wire feed smoothly through my older MIG gun liner and drive rolls?

The .045 inch diameter matches standard MIG gun liners and drive rolls for this wire size, so it will feed without changing those consumables.

How can I confirm the welds meet the 85 ksi tensile strength after I set up the wire?

Run a test coupon on the same base metal, then verify the bead appearance and have a tensile test or bend test performed to confirm the 85 ksi as-welded strength.

Does the 10 lb plastic spool come with a contact tip or do I need to buy one separately?

The box contains only the 10 lb plastic spool of ER309L wire; a compatible .045 contact tip for your gun must be purchased separately.
