　　Avesta 2507/P100TIG rod, high-alloyed, high corrosion resistant

　　ClassificationEN ISO 14343-A AWS A5.9W 25 9 4 L N ER2594

　　Characteristics and typical fields of applicationAvesta 2507/P100 is intended for welding super duplex alloys such as SAF 2507, ASTM S32760,S32550 and S31260. It can also be used for welding duplex type 2205 if extra high corrosionresistance is required, e.g. in root runs in tubes. Avesta 2507/P100 provides a ferritic-austeniticweldment that combines many of the good properties of both ferritic and austenitic steels. Weldingwithout filler bbbbl (i.e. TIG-dressing) is not allowed since the ferrite content will increase drasticallyand both mechanical and corrosion properties will be negatively affected.Structure: Austenite with 45 – 55 % ferrite.Scaling temperature: Approx. 850 °C (air).Corrosion resistance:Excellent resistance to pitting and stress corrosion cracking in chloride containing environments.Pitting resistance is in accordance with ASTM G48-A, better than 40 °C. 济南骏焊
