H00Cr24Ni13
Description:
The main component of the welding wire is carbon low C-22Cr-12Ni, which is an ultra-low C stainless steel TIG welding wire. The deposited metal is ultra-low C type, and the intergranular corrosion resistance is more excellent. The crack resistance of the deposited metal is good.
use:
Often used in petrochemical, synthetic fiber and other equipment manufactured by the same type of stainless steel structure, composite steel and dissimilar steel and other structures can also be used for nuclear reactors, pressure vessel internal transition layer surfacing and tower components welding.

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.
