Avesta Welding Rod P5 basic

Interpass temperature: Max. 150°C. Heat input: Max. 2.0 kJ/mm. Heat treatment: Generally none. For constructions that include low-alloy steels in mixed joints, a stress-relieving annealing stage may be advisable. However, this type of alloy may be susceptible to embrittlement-inducing participation in the temperature range 550 – 950°C. Structure: Austenite with 15 – 20% ferrite. Scaling temperature: Approx. 950°C (air). Corrosion resistance: Superior to 316L. The corrosion resistance obtained in the first layer when surface welding corresponds to that of ASTM 316. Approvals • Inspecta • TÜV • UDT Characteristics AVESTA P5 basic is a highly alloyed low carbon electrode. It is designed for dissimilar welding between stainless and mild or lowalloy steels but can also be used for overlay welding, providing an 18 Cr 8 Ni 2 Mo type deposit from the very first layer. P5 basic provides a somewhat better impact strength than the AC/DC type electrodes.
