Sandvik 24.13.L (Welding wire)
Datasheet updated 2012-08-17 14:53:07 (supersedes all previous editions)
Sandvik 24.13.L is suitable for joining stainless Cr-Ni steels of the 309 type, Cr-steels and dissimilar steels e.g. austenitic stainless steel to carbon or low-alloyed steels for service up to 320oC (610oF). It is used for MIG/MAG-, TIG-, plasma-arc and submerged-arc welding.

Corrosion properties- weld metal
Sandvik 24.13.L 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

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.
TIG welding
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.
Submerged-arc welding
Electrode positive is suggested for joint welding to give good penetration.
