Specifications & application fields

RW ER309L stainless welding rods are used for welding austenitic stainless steels, joining dissimilar metals, building buffer layers, joining corrosion-resistant stainless steels to low-alloy steels, and welding cladded steels.

Dissimilar joints

Stainless ↔ low alloy

Buffer layers

Before overlays

Clad steels

Reliable bonding

Shielding gas group: I1 • Mechanical data referenced with I1.

Notes

Built for transitions

Reduced cracking risk

Ideal for mixed steel combinations and difficult-to-weld joints.

Stable ductile deposit

Supports buffer layers and stainless overlay work.

Procedure control

Keep dilution consistent—especially on clad and dissimilar welds.

Final suitability depends on WPS, joint design and base metal.
