Austenitic stainless steel wire electrode for GMA (MIG/MAG) welding of dissimilar steels, difficult to weld steels, armour plates, high manganese steels, rails, crossovers. Suitable also for depositing stress relaxing buffer layers on crack sensitive base metals and hard surfacing jobs, e.g. crane wheel surfacing where high degree of pressure and dynamical loads exists. Weld metal has a high degree of corroison resistance and resistant to operating temperatures up to 300°C and non-scalling up to 850°C. Observe welding procedures, preheating temperature and avoid high admixture of base metal.

Austenitic-ferritic stainless steel wire electrode for GMA (MIG/MAG) welding of dissimilar steels and and depositing buffer layers on ferritic steels. It features high resistance to cracking and toughness, is therefore suited for joining difficult to weld steels and depositing stress-relaxing buffer layers on crack sensitive base metals. Weld metal is non-scaling up to +1100°C. Especially used in die and tool repair, crack repairs in difficult to weld steels, gear teeth repair and rebuilding, buffer layer application on cutting blades. Suitable also for welding galvanized steel plates.
