Hastelloy C2000 Pipe Maker in China, In-Stock Supply

Q: How does Hastelloy C2000 perform in terms of pitting resistance?

It is exceptionally outstanding .Its PREN typically hovers around 52.By comparison,316L stainless steel has a PREN of only around 24.This means it is virtually immune to pitting or crevice corrosion in environments with extremely high chloride concentrations or in seawater.

Q: In which specific acids is C2000 the preferred choice?

Sulfuric Acid: Especially under conditions involving moderate concentrations (30%–70%) and high temperatures. Hydrofluoric Acid: The addition of copper gives it unique resistance to this acid. Mixed Acids: When both reducing acids and oxidizing salts (such as Fe³⁺ and Cu²⁺) are present in the process,C2000 is the optimal choice.

Chemical Composition of Hastelloy C2000 Pipe, wt.%

The chemical composition of Hastelloy C2000 steel pipe is specifically designed to withstand both oxidizing and reducing chemical environments.A key feature is the deliberate addition of 1.6% copper,which distinguishes it from other C-series nickel alloys.

Element	Ni	Cr	Mo	Cu	Fe	Co	Mn	Al	Si	C	V	P	S
Nominal	59.0 Min	23.0	16.0	1.6	–
Range	Balance	22.0 – 24.0	15.0 – 17.0	1.3 – 1.9	3.0 Max	2.0 Max	0.50 Max	0.50 Max	0.08 Max	0.01 Max	0.35 Max	0.025 Max	0.01 Max

What is The Main Difference Between C2000 And C276 in Terms Of Composition?

Cr Content:
C2000 (23%) is significantly higher than C276 (16%),resulting in greater resistance to oxidation.
Cu Content:
C2000 contains copper,whereas C276 does not.
W Content:
C276 contains approximately 4% tungsten to enhance pitting resistance,while C2000 relies primarily on 16% molybdenum (Mo) to achieve this,without the addition of tungsten.

What Do “Low Carbon (C)” And “Low Silicon (Si)” Mean?

This extremely low content prevents the formation of grain boundary precipitates,such as carbides,in the heat-affected zone during welding.This means that the pipes can be used immediately after welding without the need for post-weld heat treatment.

What is The Maximum Temperature This Material Can Withstand?

Although its chemical composition provides excellent chemical stability,due to limitations in its microstructure,it is generally recommended that this material be used in environments below 427°C (800°F) to prevent the precipitation of brittle phases.

Mechanical Properties of Hastelloy C2000 Pipe

Hastelloy C2000 pipes exhibit exceptional strength and ductility at both room temperature and high temperatures.This alloy is a solution-hardened nickel-based alloy with excellent tensile strength that does not harden through heat treatment.According to ASTM B622 (seamless pipes) and ASTM B619 (welded pipes) standards,typical properties in the annealed condition are as follows:

Tensile Strength	Yield Strength	Elongation	Hardness
≥ 690 MPa(100 ksi)	≥ 310 MPa(45 ksi)	≥ 45%	≤ 100 HRB

High-Temperature Mechanical Performance

The primary advantage of C2000 steel is its corrosion resistance,yet it retains considerable strength even at high temperatures.However,for pressure-bearing applications,its service temperature is typically limited to 800°F (427°C) or below to prevent the precipitation of brittle phases.

Temperature (°F / °C)	Yield Strength (ksi / MPa)	Tensile Strength (ksi / MPa)
200°F / 93°C	46.0 / 317	107.0 / 738
400°F / 204°C	38.0 / 262	96.0 / 662
600°F / 316°C	33.6 / 232	91.2 / 629
800°F / 427°C	31.0 / 214	89.0 / 614

Physical & Elastic Properties

Modulus of Elasticity (E): 29.9 × 10⁶ psi (206 GPa)
Modulus of Rigidity (G): 11.5 × 10⁶ psi (79 GPa)
Poisson’s Ratio: 0.30
Density: 0.307 lb/in³ (8.50 g/cm³)

How Do Mechanical Properties Change At Low Temperatures?

Like most nickel-based alloys,C2000 retains excellent toughness and impact strength even at sub-zero temperatures.Unlike many carbon steels,it does not become brittle when frozen.

How Does its Hardness Compare to That of Stainless Steel?

Hastelloy C2000 pipe typically has a hardness of 80–100 HRB.This is slightly harder than standard 316L stainless steel pipe.Although it is not a “hard” wear-resistant alloy,its toughness gives it excellent impact resistance.

Applications of Hastelloy C2000 Pipe

FAQs About Hastelloy C2000 Pipe

Why are C2000 pipes typically much more expensive than stainless steel pipes?

Hastelloy C2000 pipe contains approximately 59% high-purity nickel and significant amounts of molybdenum and chromium.Furthermore,this alloy work-hardens extremely rapidly,making the requirements for drawing,welding,and heat treatment processes far more demanding than those for ordinary stainless steel.These factors directly drive up its price.
