Stainless MIG wire for 316L joints

This Westward ER316LSi spool is made for MIG welding stainless steel grades 316L and 316LN. The 0.030 in diameter suits a range of hobby and light-industrial machines. It arrives on a 2 lb plastic spool ready for DCEP polarity. Welds can be run flat, horizontal, overhead or vertical.

Consistent strength on long runs

The wire delivers a minimum yield of 64 ksi and a tensile strength of 90 ksi as welded. These figures hold across extended beads rather than only in short test coupons. Low carbon content reduces carbide precipitation during sustained heat. The silicon addition improves wetting and bead appearance over lengthy passes.

ER316LSi classification matches 316L base metal

AWS A5.9 ER316LSi is the single spec that confirms the wire matches 316L and 316LN grades. Using a different classification risks corrosion cracks or strength loss in the finished joint. Check the material grade before ordering.

Questions about this item

Does the 0.030" ER316LSi wire generate much heat when running all day on a DCEP machine?

The wire is rated for 90 ksi tensile strength and 64 ksi yield strength as welded on stainless steel grades 316L and 316LN.

What equipment must I already own to use this 2 lb plastic spool of MIG wire?

You need a MIG (GMAW) welder capable of DCEP current and a drive system that accepts 0.030 inch diameter wire on a 2 lb plastic spool.

Will this ER316LSi spool work with my older welder that only handles solid stainless wire?

Yes, it is a solid stainless steel wire classified to AWS A5.9 for flat, horizontal, vertical-up, vertical-down and overhead positions.
