Sandvik 19.9.L is used for TIG, plasma arc welding and submerged arc welding. It is suitable for joining stainless steels of the 18Cr/8Ni/ELC, and 18Cr/8Ni/Nb types for service temperatures up to 350 deg C (660 deg F). Sandvik 19.9.L is approved by TÜV-Rheinland for use at cryogenic temperatures down to 4 deg K (-269 deg C)
- Sandvik 19.9.L has good resistance to general corrosion
- Due to its low carbon content, good resistance to intercrystalline corrosion
- Good resistance to oxidizing agents
- 0.11mm/yr. rate of corrosion mean value
- 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
- 28 - 32 volt (SAW)
- 160 HV at 20 deg C hardness
- 15 - 21 W/m at 20 - 500 deg C thermal conductivity
- 18 x 10^-6 at 20 - 400 deg C co-efficient of thermal expansion
- 7.9 g/cc density
