Material Overview
CD4MCu is a high-performance cast duplex stainless steel (0Cr26Ni5Mo2Cu3) with a nominally 26Cr-6Ni alloy composition (C≤0.04) enhanced with molybdenum and copper. This material features a two-phase structure in the cast state, consisting of austenite distributed in a ferrite matrix.
Heat Treatment Process
The solution treatment temperature for CD4MCu is 1120℃, maintained for at least two hours to ensure uniform temperature, followed by slow cooling to 1010-1065℃ with a half-hour hold before quenching. This process results in a structure containing 35-40% austenite in the ferrite matrix.
Key Properties
- Yield strength approximately twice that of 19Cr-9Ni austenitic alloys
- High hardness combined with excellent corrosion resistance
- Superior resistance to stress corrosion cracking in chlorine environments
- Good tensile plasticity and impact toughness
- Can be further strengthened by precipitation hardening at 480-510℃
Chemical Composition
| C ≤0.04% | Mn ≤1.0% | Si ≤1.0% | P ≤0.04% | S ≤0.04% |
| Cr 24.5-26.5% | Ni 4.75-6.00% | Mo 1.75-2.25% | Cu 2.75-3.25% |
Performance Characteristics
CD4MCu offers exceptional performance in chemical, papermaking, food processing, and marine engineering applications, particularly for pumps, valves, and components requiring:
- Strong resistance to pitting and crevice corrosion
- Excellent performance in both oxidizing and reducing acid conditions
- High temperature strength and corrosion resistance combination
Advantages and Considerations
Advantages:
- High temperature strength maintenance
- Excellent corrosion resistance against acids, alkalis, and salts
- Good weldability and post-weld properties
- Long service life with reduced maintenance requirements
- Favorable machining characteristics
Considerations:
- Higher material cost compared to standard alloys
- Potential brittleness under certain conditions
- Sensitivity to specific chemicals like chloride ions
