(MIG Stainless Steel Wires)
▶︎ Characteristics:
It is austenitic stainless steel filler metal for welding of 29%Cr-9%Ni types. It is widely used for joining of dissimilar metals to join 300 series stainless steels to carbon or low alloy steels.
▶︎ Applications:
Typical applications include marine, re-conditioning and refurbishment industries.
▶︎ 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.
