SAF Starinox 312 P description: STARINOX 312 P is a rutile coated MMA electrode for joining difficult-to-weld steels, dissimilar steels and for wear-resistant surfacing and buffer layers. Applications include repair and maintenance welding on machines, power transmission equipment and tools. The microstructure of the higher strength weld metal consists of ferritic-austenitic Cr-Ni steel, with 30% delta-ferrite, and is highly crack resistant, rust-proof and non-scaling <1100C. Specially designed for all welding positions, it is a good compromise between weldability, bead appearance and mechanical characteristics.
