H0Cr19Ni9
Description:
The main component of the wire is 19Cr-9Ni, stainless steel TIG wire. Smooth welding, smooth and smooth weld, deposited metal corrosion resistance.
use:
It is used in the welding of 06Cr19Ni10 (SUS 304) materials such as food machinery, medical equipment, chemical fertilizer equipment, textile machinery and tank containers, pipes and the like or the welding of similar parent metal austenitic stainless steel.

Precautions:
1. Protective gas: pure Ar; flow: 9 ~ 14L / min at current of 100 ~ 200A and 14 ~ 18L / min at current of 200 ~ 300A.
2. Tungsten extension length: 3 ~ 5mm; arc length: 1 ~ 3mm.
3. Wind speed limit ≤1.0m / s; it is recommended to pass argon gas protection on the back of welding area.
4. In welding, the size of the welding wire energy directly affects the mechanical properties of the weld metal and crack resistance, should pay more attention.
5. Welding parts of the rust layer, moisture, oil, dust, etc. in addition to net.
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.
