Characteristics:
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
Applications:
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.
Notes on Usage:
- Use Spray Transfer or Short Circuit Transfer mode.
- 98%Argon – 2%O2 shielding gas is recommended.
- Preheat of the joint to minimum of 150ºC before welding.
