MH1Cr24Ni13
Description:
The main component of wire is 22Cr-12Ni. Equipped with pressure-bearing stainless steel smelting equipment JQ.SJ601, the deposited metal has good mechanical properties, crack resistance, anti-intergranular corrosion resistance. Due to high alloy content, high temperature resistance is good.
use:
Often used in pressure equipment, petrochemicals, thermal power stations and other industries. For carbon steel and stainless steel dissimilar materials welding or applied to poor toughness martensitic, pearlite stainless steel 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.
