Applications

CEWELD® CroNi 29-9 S is an austenitic-ferritic special alloy that is suitable for joining difficult-to-weld steels. It has a wide range of applications such as the repair and maintenance of machines, shafts and gear wheels, particularly in the construction machinery sector. It is also excellent for buffer layers before overlay welding and for mixed welds between steel, stainless steels or unknown steels. Very good corrosion resistance in damp, sulphurous environments, e.g. in sulphate digesters in the paper industry.
