ASTM SB163 UNS N04400 Nickel-Copper Alloy Seamless Pipe

N04400 Alloy Pipe Overview

ASTM SB163 UNS N04400 is a nickel-copper alloy seamless pipe renowned for exceptional corrosion resistance in acidic, alkaline, and marine environments. With high strength, thermal stability (up to 538°C), and superior fabricability, it’s ideal for critical applications in chemical processing, oil & gas, and marine engineering. Manufactured to ASTM SB163 standards, these pipes ensure reliability in extreme conditions.

N04400 Chemical Composition

The corrosion resistance of N04400 stems from its precise nickel-copper balance. Key elements include:

Element	Content (%)	Element	Content (%)
Nickel (Ni)	63.0 min	Copper (Cu)	28.0–34.0
Iron (Fe)	2.0 max	Manganese (Mn)	2.0 max
Carbon (C)	0.3 max	Sulfur (S)	0.024 max
Silicon (Si)	0.5 max

N04400 Equivalent Grades

N04400 alloy is globally recognized under these designations:

Standard	Equivalent Grade	Standard	Equivalent Grade
UNS	N04400	EN	NiCu30Fe
DIN	2.4360	JIS	NW4400
BS	NA 13	ASME	SB163

N04400 Mechanical Properties
