Two new Avesta Welding electrodes – an all-rounder and one considerably more specialised
|
|
Avesta 308LMo (AWS A5.4 E308LMo-17) is an all-round electrode. It is suitable not only for general welding and repair of stainless steels, but also for welding dissimilar joints between unalloyed and stainless steels. Thanks to its chemical composition, the weld metal shows good tolerance of mixing with the parent metal.
Typical analysis: C 0.02%, Si 0.8%, Cr 19.7%, Ni 9.9% and Mo 2.5%. This gives a relatively high ferrite content, 20 FN (WRC-92). Typical values for mechanical properties are: yield strength 560 N/mm2, tensile strength 700 N/mm2 and elongation 35%. Avesta 308LMo is available in 2.5, 3.25 and 4.0 mm dimensions.

Avesta 16.8.2 (AWS A5.4 E16-8-2-17) is a hybrid of 308H and 316H. It can thus be used to weld many 3XXH type stainless steels with a carbon content of 0.04 – 0.10%. The weld metal gives good creep properties along with good resistance to oxidation. A low total Cr + Mo content combined with a controlled carbon content and low ferrite content ensures good resistance to the formation of embrittling phases at high operating temperatures.
Typical analysis: C 0.05%, Si 0.45%, Mn 1.6%, Cr 15.5%, Ni 8% and Mo 1.2%. This gives a ferrite content of 0 – 2 FN. Despite the low ferrite content, the weld metal is not prone to hot cracking and the weld tolerates operating temperatures up to around 800°C.
Areas of application for Avesta 16.8.2 include the welding of catalytic crackers and furnace, superheater and steam pipe components in the petrochemical and chemical industries. Avesta 16.8.2 is available in 3.25 and 4.0 mm dimensions.
