16CrMo44 Investment Casting
This steel has good process performance and welding performance and has high lasting strength at 500~550℃. When the temperature exceeds 550°C, the anti-oxidation performance becomes worse and the creep strength is significantly reduced. When exposed to 500~550℃ for a long time, the thermal strength of steel decreases and its strength decreases.

Feature Description
This steel has good process performance and welding performance and has high lasting strength at 500~550℃. When the temperature exceeds 550°C, the anti-oxidation performance becomes worse and the creep strength is significantly reduced. When exposed to 500~550℃ for a long time, the thermal strength of steel decreases and its strength decreases.
