High Mn Autensite F.C.W:
1)resistant to high temperature
2)the shielding gas is pure CO2
3)used with the contant hardness
High Mn Autensite F.C.W
DY-YD57(Q) can be used with the hardness below 700 °C.
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.
