Material Description

Monel K500 Round Steel is a high-performance nickel-copper alloy renowned for its exceptional combination of high tensile strength, excellent fatigue resistance, and outstanding corrosion resistance. This precipitation-hardenable alloy is ideal for demanding industrial machinery applications where reliability and durability are critical.

Overview of Monel K500

Monel K500 (UNS N05500) is an age-hardenable nickel-copper alloy that retains the excellent corrosion resistance of Monel 400 but with significantly enhanced mechanical properties due to additions of aluminum and titanium. This alloy is characterized by its high strength, good toughness over a wide temperature range, and excellent performance in corrosive environments.

Chemical Composition (%)

Element	Minimum (%)	Maximum (%)
Nickel (Ni)	63.0	-
Copper (Cu)	27.0	33.0
Aluminum (Al)	2.30	3.15
Titanium (Ti)	0.35	0.85
Iron (Fe)	-	2.0
Manganese (Mn)	-	1.5
Silicon (Si)	-	0.5
Carbon (C)	-	0.25
Sulfur (S)	-	0.01

Mechanical Properties

Tensile Strength: ≥1000 MPa (up to 1200 MPa after age-hardening)
Yield Strength (0.2% Offset): ≥690 MPa (exceeds 790 MPa in age-hardened condition)
Elongation (A5 %): ≥20%
Hardness: 265-310 HB (typical), approximately HRC 25-35 after aging
Fatigue Strength: Excellent resistance in corrosive environments
Impact Toughness: Good fracture toughness (≥80J at -196°C)

Physical Properties

Density: 8.05-8.80 g/cm³
Melting Point: 1300°C - 1350°C
Elastic Modulus: 26,000 ksi
Thermal Conductivity: 22 W/m·°C
Magnetic Properties: Essentially non-magnetic

Key Characteristics and Advantages

High Strength and Hardness: Significantly enhanced through age-hardening treatments
Excellent Fatigue Resistance: Superior performance in corrosive environments like seawater
Outstanding Corrosion Resistance: Resistant to seawater, acids, alkalis, and chloride-induced stress corrosion
Good Wear Resistance: 30-50% better than standard stainless steels in abrasive environments
Wide Temperature Applicability: Maintains properties from sub-zero to 480°C
Non-Magnetic: Ideal for electronics, marine, and aerospace applications

Applications in Industrial Machinery

Pump Shafts and Impellers for marine and chemical applications
Valves and Valve Components in chemical processing and oil/gas production
Fasteners and Springs requiring high strength and corrosion fatigue resistance
Scraper Blades and Doctor Blades in paper manufacturing equipment
Wear Rings and Bushings for pumps and valves in abrasive/corrosive services
Oil & Gas Drilling Equipment including non-magnetic drill collars
Aerospace Components such as engine parts and turbine blades

Processing and Heat Treatment

Monel K500 can be strengthened by cold working and age-hardening (precipitation hardening). Typical aging is performed at 480-620°C for 4-16 hours, leading to precipitation of fine γ' phases that significantly enhance strength. Stress relieving after welding is recommended before age-hardening.

Available Forms and Specifications

Precision-cut round steel (bars, rods), also available as plates, sheets, tubes, pipes, wires, forgings, and flanges. Standard specifications include ASTM B865, AMS 4676, UNS N05500, and DIN 2.4375.

Why Choose Monel K500 Round Steel?

For industrial machinery parts subjected to high stresses, cyclic loading, and corrosive environments, Monel K500 offers exceptional reliability, versatility, and performance. Its combination of mechanical strength and corrosion resistance exceeds many stainless steels and other nickel alloys.

Typical Mechanical Properties (Aged Condition)
