説明
特徴
It is a ferrite stainless steel with good ductility in heat-treated condition. It is used for welding 17%Cr steel, overlays and thermal spraying.
アプリケーション
It is suitable for welding of 409 and 430 stainless steel types. Typical applications are used for automotive exhaust fabricators such as front pipe, bellows, flange.
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.
4. Preheat of the joint to minimum of 150°C before welding.
