Austenitic stainless steel welding wire for submerged arc welding of dissimilar steels, difficult to weld steels, armour plates, high manganese steels, rails, crossovers. Suitable also for depositing stress relieving buffer layers on crack sensitive base metals and hardsurfacing, e.g. crane wheels, cutting blades and dies where high degree of pressure and dynamical loads exists. Weld metal is resistant to operating temperatures up to 300°C and non-scalling up to 850°C and also highly corrosion resistant. Used in combination with SIF 501 and SIF 502 submerged arc welding fluxes. Depending on chemical composition of base metal, proper welding procedure, preheating and interpass temperatures shall be applied by also avoiding high admixture of base metal.
