Properties And Applications

Stabilized austenitic stainless steel welding wire for submerged arc welding of unstabilized and stabilized corrosion resisting Cr-Ni steels. Used in combination with SIF 501 and SIF 502 submerged arc welding fluxes. Generally used for welding pipes, tanks and equipments in food, beverage, chemical and pharmaceutical industries. Stabilized with Cb (Nb) and resistant to intergranular corrosion. Weld metal is suitable for operating temperatures of up to 400°C, non-scaling up to 800°C, in air and oxidizing combustion gases.
