Exaton Sandvik R25.10.4.L

For welding of SuperDuplex steels.

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 TIG-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:

The parameters for TIG welding depend largely upon the base metal thickness and the welding application. Electrode negative and a shielding gas of argon + 2-3 % N2 should be used.
