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.

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.
