Thermanit 22/09德國蒂森焊絲

Thermanit 22/09 TIG rod
Classifications high-alloyed
EN ISO 14343-A: AWS A5.9:
W 22 9 3 N L ER2209
Characteristics and field of use
Duplex stainless steel resistant to intercrystalline corrosion and wet corrosion up to 250 °C (482
°F). Good resistance to stress corrosion cracking in chlorine- and hydrogen sulphide-bearing
environment. High Cr- and Mo-contents provide resistance to pitting corrosion. For joining and
surfacing work with matching and similar austenitc steels/cast steel grades. Attention must be paid
to embrittlement susceptibility of the parent metal.
