Exaton Sandvik 25.10.4.L

For welding of SuperDuplex steels.

EN ISO 14343 25 9 4 N L
SFA/AWS A5.9 ER2594

General description:

25.10.4.L is used for welding of Sandvik SAF 2507 and other super-duplex steels. The grade is characterized by excellent resistance to stress corrosion in chloride-bearing environments and excellent resistance to pitting and crevice corrosion. 25.10.4.L can also be used for welding Sandvik SAF 2205 and corresponding duplex steels when the highest possible corrosion resistance is required. It is used for MIG/MAG welding.

The interpass temperature should be kept below 150°C and the heat input between 0.2 and 1.5kJ/mm for joint welding. Preheating is normally not recommended.

Recommended welding data:

Electrode positive is used to give good penetration in all types of welded joint. Short-arc welding is used with light gauge material of less than about 3 mm, in depositing root runs, and in welding out-of-flat positions. The higher the inductance in short-arc welding, the higher the fluidity of the molten pool. Spray-arc welding is normally used for heavier gauge material.
