H0Cr21Ni10
Description:
The main wire is 18Cr-8Ni, stainless steel TIG wire. Smooth welding, shallow penetration, no spatter, weld smooth formation, can be single-sided welding double-sided forming. Deposited metal cracking good performance, excellent corrosion resistance.
use:
For 12Cr18Ni9 (SUS 302), 06Cr19Ni10 (SUS 304) type austenitic stainless steel and similar base metal welding, is also commonly used in sheet metal welding.
Deposited metal chemical composition (%)

Reference current (AC, DC - )
Diameter (mm) | 1.6 | 2.0 | 2.5 | 3.2 |
Welding current (A) | 50 ~ 100 | 100 ~ 200 | 200 ~ 300 | 300 ~ 400 |
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.
