JIS Z 3321 : Y309L
▶︎ Characteristics: stainless steel TIG rod
It is austenitic stainless steel filler metal with good general oxidation resistance at high temperature. It is excellent corrosion and heat resistance, ideal for welding and building up parts for heat treatment and case hardening furnaces and other burners.
▶︎ Applications:
It is suitable for welding of 25%Cr-20%Ni stainless steel and dissimilar steels. Typical application include marine, re-conditioning and refurbishment industries.
▶︎ Notes on Usage:
1. For TIG process, use DC(-) current, Argo 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.
