Characteristics of ASTM A890 CD4MCu and application of castings

ASTM A890 CD4MCu is a Fe-Cr-Ni-Cu-Mo alloy with ferrite and austenite dual phase structure. The combination of medium strength and hardness with good ductility and impact properties makes the alloy has better wear resistance Resistance or corrosion resistance.


Compared with standard stainless steel, CD4MCu has better resistance to stress corrosion cracking and less pitting corrosion. It has higher strength and is therefore more durable.


When selecting the component materials of the pump, it is necessary to evaluate the pump liquid, specific gravity and pH value, GPM, total dynamic head, pump type and speed and other factors, and whether the pump runs intermittently or continuously. An engineer can help you choose the best solution for your application.
