Material Description

CD4MCU is a duplex (ferritic-austenitic) stainless steel known for its high strength, excellent corrosion resistance in chloride environments, and good wear resistance. The balanced microstructure of austenite and ferrite, combined with copper and molybdenum additions, provides enhanced performance in aggressive industrial environments.

Chemical Composition (Typical %)

Carbon (C): ≤0.04
Chromium (Cr): 24.5-26.5
Nickel (Ni): 4.75-6.00
Molybdenum (Mo): 1.75-2.25
Copper (Cu): 2.75-3.25
Nitrogen (N): 0.10-0.25
Iron (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

Material 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 against pitting, crevice corrosion, and stress corrosion cracking in chloride-rich environments
High strength with nearly double the yield strength of standard austenitic steels like 316L
Excellent wear and erosion resistance for abrasive conditions
Good weldability with proper techniques including low heat input and post-weld annealing

Similar Grades

F51 (1.4462) / 2205: Lower copper content, widely used duplex steel
F55 (1.4501) / 2507: Super duplex with higher chromium, molybdenum, and nickel
CD3MN (F53): Another duplex grade without copper

Industrial Applications

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