Chemical composition (nominal) %
Sandvik 24.13.LHF welding wire is used for TIG, plasma-arc, MIG and submerged-arc welding. It is particularly suitable for overlay welding and joining dissimilar steels, for example austenitic stainless steels to low alloyed or non alloyed steels. It has excellent resistance to hot cracking due to its enhanced ferrite content.
Forms of supply
Sandvik 24.13.LHF is supplied as wire and straight rods.
Weld metal characteristics
Sandvik 24.13.LHF gives a microstructure with an austenitic matrix and a ferrite content of 15-16FN according to the DeLong diagram.
MIG TIG – typical for non-heat treated weld metal
|Temperature||°C (°F)||20 (68)|
|Yield strength, RP0.2||MPa (ksi)||410 (60)|

Sandvik 24.13.LHF is normally used for joints between non alloyed or low alloyed steels and stainless steels, where resistance to corrosion is of secondary importance.
Recommended welding data
Electrode positive is used to give good penetration in all types of welded joint. The following table shows common conditions for MIG welding.
|Wire diameter||Wire feed||Current||Voltage||Gas|
1)Pulse parameters: Peak current 300 - 400 A
Background current 50 - 150 A
Frequency 80 - 120 Hz
Sandvik can provide recommendations for shielding gases.
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.
The parameters for TIG welding depend largely upon the base metal thickness and the welding application.
Electrode negative and a shielding gas of argon or helium should be used to prevent oxidation of the weld metal.
Electrode positive is suggested for joint welding to give good penetration.
Recommended welding flux is Sandvik 15W.
