Properties and Applications

Basic coated electrode for joining dissimilar steels and depositing buffer layer before hardfacing and claddings on ferritic steels. The weld metal consists of austenitic Cr-Ni-Mn steel with possible small amounts of delta ferrite. The weld metal is highly crack resistant and therefore suited to joining difficult to weld steels and depositing stress relaxing buffer layers on crack sensitive base metal prior hardfacing deposits. Weld metal work hardens by impact and pressure. Suitable for armour plates, rail, cross-over, crane wheels, idlers, which are subjected to dynamically loading, pressure, impact and abrasion. It is non-scaling up to 850°C and highest operating temperature for dissimilar steel joints is 300°C. In the case of higher temperatures, use ENI 422 electrodes. Used with DCEP (DC+)
