MH00Cr21Ni10
Description:
The main component of the wire is ultra-low C-18Cr-8Ni. Equipped with JQ.SJ601 stainless steel and heat-resistant steel for alkaline sintering flux, the deposited metal has good mechanical properties and resistance to intergranular corrosion resistance, crack resistance is good. Due to low carbon content, corrosion resistance is more excellent.
use:
Widely used in petrochemical and other industries, such as 022Cr18Ni9 (SUS 304L) 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.
