H1Cr24Ni13
Description:
The main components of the wire is 22Cr-12Ni, stainless steel TIG wire. Smooth welding, weld smooth and smooth, deposited metal has good mechanical properties, crack resistance and oxidation resistance, but also has excellent corrosion resistance.
use:
Often used to weld the same type of stainless steel, stainless steel lining, dissimilar steel (06Cr19Ni10 and low carbon steel) and high Cr, high Mn 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.
