Stainless Filler Metal Selection Guide

ASME SFA 5.9

SFA 5.9 / A 5.9 is the filler metal specification for Bare Stainless Steel Welding Electrodes and Rods.

Filler metals with the 5.9 specification consist of solid wires or rods and apply to GTAW, GMAW, and SAW wires.

ASME SFA 5.4

SFA 5.4 / A 5.4 is the filler metal specification for Stainless Steel Electrodes for SMAW.

ASME SFA 5.22

SFA 5.22 / A 5.22 is the filler metal specification for Stainless Steel Electrodes for FCAW and Flux Cored Rods for GTAW.
