MH0Cr19Ni9
Description:
The main component of wire is 19Cr-9Ni. Equipped with JQ.SJ601 stainless steel alkaline sintered flux, the deposited metal has good mechanical properties, crack resistance, resistance to intergranular corrosion.
use:
Widely used in food machinery, medical equipment, fertilizer equipment, textile machinery and other components and tank containers, pipes and other materials such as 06Cr19Ni10 (SUS 304) 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.
