Valve Stem Nickel Alloy Valve Parts Hastelloy C-276 UNS N10276 For Petrochemical

Valve Stem Nickel Alloy Valve Parts Petrochemical Hastelloy C-276 UNS N10276

Hastelloy C-276 is a nickel-molybdenum-chromium superalloy with an addition of tungsten designed to have excellent corrosion resistance in a wide range of severe environments. This material is known for its outstanding resistance to pitting, crevice corrosion, and stress-corrosion cracking.

Composition:

Ni	Co	Cr	Mo	W	P	Fe
Remainder	2.5max	14.5-16.5	15.0-17.0	3.0-4.5	0.04max	4.0-7.0
Si	Mn	C	V	S
0.08max	1.0max	0.01max	0.35max	0.03max

Physical Properties:

Density: Around 8.87 g/cm³
Melting Point: Approx. 1325-1370 °C (2417-2500 °F)
Thermal Conductivity: Varies with temperature, approximately 10.1 W/m·K at 20 °C
Coefficient of Thermal Expansion: 11.2 µm/m-°C (20-100 °C)

Mechanical Properties:

Tensile Strength: 690 MPa minimum
Yield Strength (0.2% Offset): 283 MPa minimum
Elongation: 40% minimum in 50 mm

Corrosion Resistance:

Hastelloy C-276 offers superb resistance to a wide variety of chemical environments, including:

Strong oxidizers like ferric and cupric chlorides
Hot contaminated media (organic and inorganic)
Chlorine
Formic and acetic acids
Acetic anhydride
Seawater and brine solutions

Applications:

Due to its high corrosion resistance, a valve stem made from Hastelloy C-276 is particularly suitable for harsh environments, such as:

Chemical processing
Pollution control
Pulp and paper production
Industrial and municipal waste treatment
Pharmaceutical and food processing equipment

DINGSCO favors Hastelloy C-276 for valve components, especially valve stems, in applications where standard stainless steel or other materials might fail due to corrosion. Furthermore, its durability and reliability extend the lifespan of the valves, ensuring operational integrity even under harsh conditions.
