説明
特徴
It is modified 309L austenitic stainless steel to higher silicon content to improve welding properties such as higher welding speed.
アプリケーション
It is used for oil and gas refineries, include welding of 22%Cr-12%Ni stainless steel, AISI 304L,316L in chemical and welding of dissimilar base metals of stainless and carbon steels.
使用上の注意
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.
