H0Cr19Ni14Mo3
Description:
The main component of the wire is 19Cr-14Ni-3Mo, stainless steel TIG wire. Due to the addition of SUS 316 based on the alloy elements Cr, Ni, Mo content, weld metal corrosion resistance, heat resistance, crack resistance even more excellent. And for acetic acid, sulfurous acid, phosphoric acid and salts of corrosion resistance is also more excellent, especially anti-Cl ion pitting performance is stronger.
use:
Often used in petrochemical, fertilizer equipment, such as 06Cr17Ni12Mo2 (SUS 316) and other materials 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.
