A 5.4kg packet of 4.0mm E309MoL-17 P5 AC/DC highly alloyed, low carbon covered electrodes from Avesta.

Characteristics:
AVESTA P5 is a highly alloyed low carbon electrode corresponding to AWS A5.4 E309MoL-17. The electrode is designed for dissimilar welding between stainless and mild or low-alloy steels but can also be used for overlay welding, providing an 18 Cr 8 Ni 2 Mo deposit from the very first layer. It can also be used for welding highstrength steels such as HardoxÂ® and ArmoxÂ®.

Interpass temperature: Max. 150Â°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 precipitation in the temperature range 550 â€“ 950Â°C.

Structure: Austenite with 15 â€“ 20% ferrite.

Scaling temperature: Approx. 950Â°C (air).

Corrosion resistance: Superior to 316L. The corrosion resistance obtained in the first layer when surface welding corresponds to that of ASTM 316.
