MI 307SI (K300 MS PRE)

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 hardfacing jobs, e.g. crane wheel surfacing where high degree of pressure and dynamical loads exists. Weld metal has a high degree of corrosion 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.
