제품 설명

ASTM B283 C70620 CuNi 90/10 Copper Alloy Steel Flange For Marine And Offshore Engineering

ASTM B283, corresponding to ASME SB283, is a standard specification for copper and copper alloy forgings, applicable to copper and copper alloy forgings produced by hot pressing, including flanges, fittings, and other pressure-bearing components. UNS C70620 is a 90/10 copper-nickel alloy (90% copper - 10% nickel), optimized for welding applications and marine conditions based on the standard 90-10 copper-nickel alloy UNS C70600, with impurity control improvements.

The standard explicitly states: "Copper Alloys UNS Nos. C70620 and C71520 are for product intended for welding applications"—this is a core distinction between C70620 and the general-purpose C70600 material.

ASTM B283 C70620 flanges are high-performance copper-nickel alloy forged flange solutions for marine engineering, seawater pipeline systems, desalination equipment, and chemical corrosion-resistant pipelines. They offer excellent corrosion resistance, good weldability, and stable mechanical properties in seawater environments.

Chemical Composition (UNS C70620)
Element	Content Range (%)	Standard Reference
Cu (Copper)	≥ 86.5	ASTM B283 / UNS C70620
Ni (Nickel)	9.0 – 11.0	ASTM B283 / UNS C70620
Fe (Iron)	1.0 – 1.8	ASTM B283 / UNS C70620
Mn (Manganese)	≤ 1.0	ASTM B283 / UNS C70620
Zn (Zinc)	≤ 0.50	ASTM B283 (welding grade)
Pb (Lead)	≤ 0.02	ASTM B283 (welding grade)
C (Carbon)	≤ 0.05	ASTM B283 (welding grade)
P (Phosphorus)	≤ 0.02	ASTM B283 (welding grade)
S (Sulfur)	≤ 0.02	ASTM B283 (welding grade)

Mechanical Properties (ASME SB283 / ASTM B283 Standard Minimum)
Condition	Size Range	Tensile Strength (MPa)	Yield Strength (MPa)	Elongation (%)	Standard Reference
Hot forged air cooled (M10)	All sizes	≥ 276 (40 ksi)	≥ 103 (15 ksi)	≥ 30	ASTM B283
Hot forged air cooled (M10)	Specific cross-section	≥ 310 (45 ksi)	≥ 124 (18 ksi)	≥ 30	ASTM B283

Physical Properties (Typical Values, 20°C Annealed)
Parameter	Value	Unit
Density	8.89	g/cm³
Elastic Modulus	130	GPa
Thermal Conductivity (20°C)	50.2	W/(m·K)
Specific Heat Capacity	0.38	J/(g·K)
Coefficient of Linear Expansion (20-300°C)	19	×10⁻⁶/K
Electrical Conductivity	5	MS/m (approx. 9% IACS)
Melting Range	1100 – 1145	°C

Core Differences Between C70620 and C70600
Comparison Item	C70620 (Welding Grade)	C70600 (Standard Grade)
Weldability Design	Specifically designed for welding applications; standard explicitly states "intended for welding applications"	Can be used for welding, but impurity limits are less strict than C70620
Impurity Control (Zn, Pb, C, P, S)	Zn ≤0.50%, Pb ≤0.02%, C ≤0.05%, P ≤0.02%, S ≤0.02%	Zn ≤1.0%, Pb ≤0.05%, relatively looser impurity control
Iron (Fe) Content	1.0% – 1.8%	1.0% – 1.8% (essentially the same)
Seawater Corrosion Resistance	Good (welding grade)	Good (general grade)
Cost	Between C70600 and high-purity nickel alloys	Lower

Applications:

Marine Engineering and Shipbuilding: Flange connections for seawater cooling systems, fire protection systems, ballast water pipelines, and seawater delivery pipelines.
Seawater Desalination Plants: Seawater intake, pretreatment, and high-pressure pump inlet/outlet flanges.
Coastal Power Plants: Condenser and cooler connection flanges for seawater circulating cooling system pipelines.
Offshore Oil and Gas Platforms: Seawater injection systems, fire water pipelines, and public seawater systems.
Chemical and Process Industries: Corrosion-resistant pipeline flanges for chloride-containing media.

Fully meets the rigorous requirements of TEMA R standards. We used these SA266 Grade 2N flanges for a refinery project in Texas. The machining precision is impressive, and the sealing face finish is absolutely perfect.

The packaging was very solid; even after long-distance sea freight, there were no dents on the sealing faces.

We were looking for a reliable supplier for offshore platforms, and the quality of these tube side flanges exceeded expectations. The forging flow lines of the SA266 Gr.2N are very intact.
