Characteristics: stainless steel TIG rod
It is the low carbon content designed to prevent intergranular corrosion. It is used to join similar 309L alloys or join 300 series stainless steels like 316 grade. to carbon or low alloy steels.
Applications:
It is used for oil and gas refineries, include welding of AISI 309 in chemical and welding of dissimilar base metals of stainless and carbon steels.
Notes on Usage:
- For TIG process, use DC(-) current , Argon Shield and Tungsten Electrode.
