Description
Characteristics:
It is austenitic stainless steel filler metal for welding of 18%Cr-12%Ni-2%Mo types. The
molybdenum increased pitting corrosion resistance. The low carbon content improved
intergranular corrosion.
Applications:
Typical applications include welding of 18%Cr-12%Ni-2%Mo stainless steel in chemical,
oil and gas refineries.
Notes on Usage:
1. For TIG process, use DC(-) current, Argon Shield and Tungsten Electrode.
2. For MIG process, use Spray Transfer or Short Circuit Transfer mode.
3. 98%Argon – 2%O2 shielding gas is recommended in MIG process.
