Sandvik 19.12.3.L is a filler material for joining stainless CrNiMo and CrNi steels, stabilized or non-stabilized, e.g. ASTM 316, 316L and 316Ti as well as 304, 304L, 321 and 347, used for service temperatures up to 400 deg C (750 deg F), stainless Cr steels with max 19% Cr. Sandvik 19.12.3.L is available as wire and rods for MIG/MAG, TIG, plasma-arc and submerged-arc welding
- Sandvik 19.12.3L has good resistance to general corrosion
- Due to its low carbon content, good resistance to intercrystalline corrosion
- It also has good resistance to pitting corrosion due to the balanced molybdenum content
- 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
- 30 - 35 volt (SAW)
- 160 HV At 20 deg C hardness
- 15 - 20 W/m at 20 - 500 deg C thermal conductivity
