H00Cr19Ni12Mo2
Description:
The main component of the wire is ultra-low C-18Cr-12Ni-2Mo, stainless steel MIG wire, all-position welding. Excellent welding workability - smooth wire feeding, stable arc, beautiful appearance, very few splashes. Because of Mo, for acetic acid, sulfurous acid, phosphoric acid and salt corrosion resistance.
use:
Often used in petrochemical, fertilizer equipment, such as 022Cr17Ni12Mo2 (SUS 316L) and other materials welding.

Precautions:
1. Protective gas: pay attention to the purity of the protective gas mixture ratio recommended Ar + 1 ~ 3% O2.
2. Gas flow: 20 ~ 25L / min.
3. Dry elongation: 15 ~ 25mm.
4. The welding parts of the rust layer, moisture, oil, dust, etc. in addition to net.
5. Outdoor welding, when the wind speed is greater than 1.5m / s windbreak measures should be taken, there must be appropriate windbreak measures to prevent the occurrence of pores.
The above suggestions are for reference only, in the specific operation to the scene prevail. If necessary, process assessment and then determine the welding program.
