Characteristics:
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 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:
1. For MIG process, use Spray Transfer or Short Circuit Transfer mode.
2. 98%Argon – 2%O2 shielding gas is recommended in MIG process.
