Applications and Features

( 1 ) Weld metal is austenitic structure with 22.5% Cr-12% Ni.

( 2 ) Excellent weldability and crack resistance due to proper ferrite content in the weld metal.

( 3 ) Stable arc, good slag removal, low spatters, X-ray quality welds and good penetration.

( 4 ) Suitable for joining 304 stainless steel to carbon steel or low alloy steel.
