MH0Cr19Ni12Mo2
Description:
The main wire is 18Cr-12Ni-2Mo. Equipped with JQ.SJ601 stainless steel alkaline sintered flux, the deposited metal has good mechanical properties, crack resistance, resistance to intergranular corrosion. Due to high alloy content, excellent corrosion resistance.
use:
Often used in petrochemical, fertilizer equipment, such as 06Cr17Ni12Mo2 (SUS 316) and other materials welding.

Precautions:
1. Welding temperature between the proposed control at about 150 ℃. Small and medium size multi-channel multi-layer welding, pay attention to control the welding line energy.
2. Welding parts of the rust layer, moisture, oil, dust, etc. really want to clean up.
3 flux before use to be 300 ~ 350 ℃ baking 2h.
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.
