설명
특성:
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.
애플리케이션:
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.
사용 시 참고 사항:
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.
