Nickel Buttweld Fittings
Nickel Buttweld Fittings are essential piping components designed to connect, redirect, or terminate piping systems with maximum reliability and leak-proof performance. Manufactured using high-purity nickel alloys such as Nickel 200 and Nickel 201, these fittings are valued for their exceptional corrosion resistance, high mechanical strength, and excellent thermal and electrical conductivity.
Buttweld fittings are joined to pipes by welding, creating a permanent, strong connection capable of withstanding high pressure and stress. Nickel buttweld fittings are widely used in industries that demand purity, strength, and resistance to aggressive chemicals—such as chemical processing, food production, marine engineering, pharmaceuticals, and power generation.
Chemical Composition of Nickel Buttweld Fittings
The unique properties of these fittings are derived from their controlled chemical compositions:
Nickel 200
C: 0.15% max
S: 0.01% max
Cu: 0.25% max
Mn: 0.35% max
Si: 0.35% max
Ni: 99.0% min
Fe: 0.40% max
Nickel 201
C: 0.02% max
S: 0.01% max
Cu: 0.25% max
Mn: 0.35% max
Si: 0.35% max
Ni: 99.0% min
Fe: 0.40% max
Nickel 200 is a commercially pure wrought nickel, while Nickel 201 has a lower carbon content, making it particularly suitable for applications involving higher temperatures where resistance to graphitization is critical.
Mechanical Properties of Nickel Buttweld Fittings
Both Nickel 200 and Nickel 201 exhibit outstanding mechanical characteristics:
Nickel 200

Tensile Strength: 462 MPa (67,000 psi)
Yield Strength (0.2% Offset): 148 MPa (21,500 psi)
Elongation: 45%
Nickel 201
Melting Point: 1446 °C (2635 °F)
Density: 8.9 g/cm³
Tensile Strength: 462 MPa (67,000 psi)
Yield Strength (0.2% Offset): 148 MPa (21,500 psi)
Elongation: 45%
These mechanical values ensure excellent formability, toughness, and durability even in demanding conditions.
Types of Nickel Buttweld Fittings
Nickel buttweld fittings are manufactured in different shapes and sizes to meet diverse piping requirements:
