CD4MCu Stainless Steel for
Corrosive and Abrasive Applications
As an option, Global Pump provides it's full line of outstanding Trash and High Head pumps in CD4MCu, a high grade duplex stainless steel, for applications where corrosion and/or abrasion are a concern.
CD4MCu is an Fe-Cr-Ni-Cu-Mo alloy with a duplex structure of ferrite and austenite. Moderately high strength and hardness are combined with good ductility and impact properties, resulting in an alloy with superior resistance to abrasion or erosion-corrosion.
CD4MCu provides significantly better stress/corrosive cracking resistance, and less pitting than standard stainless steel. It has a higher strength and thus is more durable.
Many factors must be evaluated when selecting pump end component materials including the liquid being pumped, specific gravity and pH level, GPM, Total Dynamic Head, pump type and speed, and whether the pump will run intermittently or continuously. Global Pump engineers can help select the best solution for your application.
- Corrosion and pitting resistance
- Better for abrasive applications
- Higher strength than standard stainless steel
- Improved ductility and weldability
- Better resistance to embrittlement
Superior corrosion and abrasion ability make CD4MCu ideal for varied applications in these industries:
- Industrial Process
