A 5.4: E 312-16
EN ISO
3581-A: E 29 9 R 12
Applications
This austenitic-ferritic special alloy is suitable for joining steels that are difficult to weld. Varied application in repair and maintenance of machines, shafts, gearwheels, especially in the field of building machinery. Also excellent for buffer layers before Hardfacing and for dissimilar welding between steel, stainless steels or unknown steels. Very good corrosion resistance in wet, sulphurous environments, e.g. in sulphate fermenters in the paper industry.
