What is CD4MCu?
CD4MCu is a duplex stainless steel that provides a unique combination of high strength and corrosion resistance. It features a balanced structure consisting of ferrite and austenite, providing it with more enhanced physical properties than standard stainless-steel types. In fact, this alloy is nearly twice as strong as conventional stainless steels, making it a great choice for applications which require materials with higher structural integrity.
Key Benefits of CD4MCu
- Corrosion Resistance: CD4MCu’s duplex stainless-steel structure provides exceptional resistance to pitting, chloride induced stress corrosion cracking, and crevice corrosion. These issues are common in applications involving wastewater and chemical handling.
- Erosion Resistance: Abrasive fluids, like sand-laden water, overtime cause wear and tear on pumps, which can affect their overall performance and lifespan. CD4MCu provides superior erosion resistance, reducing maintenance needs and extending the lifespan of pumps.
- Strength and Durability: Its robust structure offers high tensile and yield strength, allowing it to maintain structural integrity under extreme pressures and demanding operations without failure. This increased strength and durability makes it ideal for high-stress applications.
- Heat Resistance: CD4MCu boasts excellent heat resistance, making it well-suited for jobs involving high temperatures. It also has a resistance to oxidation and thermal fatigue, ensuring maintained performance during chemical processing or high temperature fluid handling jobs.
Conclusion
CD4MCu is a widely used and valued material of construction for pumping applications due to its wide array of structural and physical benefits. 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 intermittent or continuous. Global Pump engineers can help select the best solution for your application.
