Super Duplex (2507) GMAW-GTAW Solid wires




Super Duplex (2507)

 
TYPE 
Mag filler metal for welding the so called Super Duplex types of stainless steels.
APPLICATIONS 
Used for pipe work and general fabrication in the offshore oil and gas and chemical process industries for welding SAF 2507, ASTM S32760 (ZERON 100),S32550 and S31260. It can also be used for welding duplex type 2205 Also suitable for cladding on standard steels.
PROPERTIES 

2507 grade is characterized by excellent resistance to stress corrosion in chloride-bearing environments and excellent resistance to pitting and crevice corrosion.
