A stainless welding wire suitable for joining dissimilar metals, such as welding carbon steel to stainless steel—particularly in applications involving steels with a high nickel (Ni) content. Welding with 312 wire produces a weld metal that contains a high proportion of ferrite within an overall austenitic matrix. Thanks to the presence of strong austenite-forming elements that provide significant dilution, such as nickel (Ni), the microstructure remains dual-phase, which ensures high resistance to hot cracking. It is not recommended for use in applications operating above 300°C, nor for welding components that require post-weld heat treatment.
