Chemical composition (nominal) %
Sandvik 24.13.Si is particularly suited for MIG welding but can also be used for TIG and PAW. It can be used for joining stainless steels of the 18Cr/8Ni type when higher corrosion resistance is desired in the weld metal. It can also be used for dissimilar joints, e.g. austenitic steels to low alloyed steels.
Forms of supply
Sandvik 24.13.Si is supplied as wire and straight rods.
Weld metal characteristics
Sandvik 24.13.Si gives a microstructure with an austenitic matrix and a ferrite content of about 10FN according to the DeLong diagram.

Sandvik 24.13.Si 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.

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.
