SIDER 312 Stainless Steel SAW Wire

SIDER 312 Stainless Steel SAW Wire

Filler metal SIDER 312 is valuable for welding dissimilar joints, especially if one of the base metals is a stainless high in nickel content. The deposit is two-phase, high in ferrite.
Even with considerable dilution with austenite forming elements, such as nickel, the microstructure is two-phase and thus highly resistant to weld metal cracks and fissures.
SIDER 312 is utilized for welding stainless steels to mild steels and for welding high strength steels that are difficult to weld with ferritic electrodes.
This wire also joins stainless steels where high strength or wear resistance is essential.
Service temperatures should be below 430°C (800°F) to prevent formation of secondary brittle phases.
