Mn Autensite welding wire

Mn Autensite welding wire:
1)resistant to high temperature
2)Ni,Mo, V are added for stable austenite and dispersion carbide
Mn Autensite welding wire:
DY-YD57(M) can be used with the hardness below 700 °C, cocontaining 16%Mn - 16% Cr.

APPLICATION

Mainly used for surfacing parts that work in the conditions high temperature and heavy impact , such as guide plate of hot mill , hot forging die , valve , etc. The shielding gas is pure CO2 or Ar+CO2.
