Introduction

CD4MCU is a duplex (ferritic-austenitic) stainless steel known for its high strength, excellent corrosion resistance (especially in chloride environments), and good wear resistance. It contains a balanced microstructure of austenite and ferrite, along with additions of copper (Cu) and molybdenum (Mo) for enhanced performance in aggressive environments.

Key Parameters

Chemical Composition (Typical %)
- C: ≤0.04
- Cr: 24.5–26.5
- Ni: 4.75–6.00
- Mo: 1.75–2.25
- Cu: 2.75–3.25
- N: 0.10–0.25
- Fe: Balance
Mechanical Properties
- Tensile Strength: 750–1000 MPa
- Yield Strength: ≥550 MPa
- Elongation: ≥15%
- Hardness: ≤290 HB
Physical Properties
- Density: ~7.8 g/cm³
- Melting Point: ~1420–1460°C

Standards

ASTM A995/A995M (Castings for pressure-containing parts)
ASTM A890 (Similar duplex stainless steel castings)
UNS J93370 (Unified Numbering System designation)

Key Features

Superior Corrosion Resistance: Resists pitting, crevice corrosion, and stress corrosion cracking (SCC) in chloride-rich environments (e.g., seawater, chemical processing).
High Strength: Nearly double the yield strength of standard austenitic steels (e.g., 316L).
Wear & Erosion Resistance: Ideal for abrasive/erosive conditions.
Good Weldability: Requires proper techniques (e.g., low heat input, post-weld annealing).

Similar Grades

F51 (1.4462) / 2205: Lower Cu content, widely used duplex steel.
F55 (1.4501) / 2507: Super duplex with higher Cr, Mo, and Ni.
CD3MN (F53): Another duplex grade but without Cu.

Applications

Oil & Gas: Subsea components, valves, pumps.
Chemical Processing: Reactors, heat exchangers, piping.
Marine Engineering: Propeller shafts, seawater systems.
Power Plants: Flue gas desulfurization (FGD) systems.
Pulp & Paper Industry: Bleaching equipment.
