Avesta 2205

Avesta 2205

High corrosion resistant Duplex Stainless Steel filler rod

Avesta 2205 is primarily designed for welding the duplex grade Outokumpu 2205 and similar but it can also be used for SAF 2304 type of steels. Avesta 2205 provides a ferritic-austenitic weldment that combines many of the good properties of both ferritic and austenitic stainless steels. Welding without filler metal (i.e. TIG-dressing) is not allowed since the ferrite content will increase drastically and both mechanical and corrosion properties will be negatively affected.

Structure: Austenite with 45 – 55 % ferrite.

Scaling temperature: Approx. 850 °C (air).

Corrosion resistance:Very good resistance to pitting and stress corrosion cracking in chloride containing environments.

  • Spec: AWS A5.9 ER2209
  • Wire Diameter: 1.6mm, 2.4mm
  • Approvals: TÜV, DB, DNV, CE




Avesta 309L

Avesta 309L

High corrosion resistant Stainless Steel

Avesta 309L is a high-alloy 23 Cr 13 Ni wire primarily intended for surfacing of low-alloy steels and dissimilar welding between mild steel and stainless steels, offering a ductile and crack resistant weldment. The chemical composition, when surfacing, is equivalent to that of ASTM 304 from the first run. One or two layers of 309L are usually combined with a final layer of 308L, 316L or 347.

Structure: Austenite with 5 – 10 % ferrite.

Scaling temperature: Approx. 1000 °C (air).

Corrosion resistance: Superior to type 308L. When fur facing on mild steel a corrosion resistance equivalent to ASTM 304 is obtained at the first bead.

  • Wire Diameter: 1.6mm, 2.4mm
  • Approvals: DNV GL
