What Is Hastelloy C4 Round Bar?
Hastelloy C4 Round Bar is a nickel-based corrosion-resistant alloy used for demanding industrial environments where resistance to corrosion and thermal conditions is important.
The material is commercially known as HASTELLOY C-4 or Alloy C-4 and is identified internationally by UNS N06455 and Werkstoff 2.4610.
For procurement and engineering documentation, these designations can be used together:
Hastelloy C-4 / Alloy C-4 / UNS N06455 / W.Nr. 2.4610 / ASTM B574
Haynes International identifies HASTELLOY C-4 as N06455 and lists DIN 17744 No. 2.4610 NiMo16Cr16Ti. Its specifications include B574/SB574 for billet, rod and bar.
Manan Steel & Metals lists Hastelloy C-4 within its Hastelloy round-bar product range.
Hastelloy C4 International Designations
Different countries, engineering companies and procurement departments may refer to the same material using different designations.
| Identification | Hastelloy C4 |
|---|---|
| Commercial Name | HASTELLOY C-4 |
| Alloy Name | Alloy C-4 |
| UNS | N06455 |
| Werkstoff Number | 2.4610 |
| DIN | NiMo16Cr16Ti |
| ASTM Bar/Rod | B574 |
| ASME | SB574 |
| Material Family | Nickel-Chromium-Molybdenum Alloy |
Using the UNS number in an enquiry can reduce ambiguity, particularly when purchasing specialty alloys internationally.
For example:
Hastelloy C4 Round Bar – UNS N06455 – ASTM B574
is considerably more precise than simply requesting “C4 bar.”
Hastelloy C4 Chemical Composition
Hastelloy C4 is a nickel-based alloy containing significant chromium and molybdenum, with titanium as a stabilizing addition.
Representative composition requirements include:
| Element | Typical / Specified Characteristic |
|---|---|
| Nickel | Balance |
| Chromium | Approximately 16% |
| Molybdenum | Approximately 16% |
| Titanium | Controlled addition |
| Iron | Controlled |
| Carbon | Low |
| Silicon | Controlled |
| Manganese | Controlled |
The exact chemical limits depend on the applicable product specification and should be verified against the relevant standard and Material Test Certificate.
ASTM B574 includes UNS N06455 among the low-carbon nickel-chromium-molybdenum alloys covered by the specification.
For critical applications, the purchasing specification should always take precedence over general website composition information.
Key Properties of Hastelloy C4
Hastelloy C4 Round Bar is selected for applications requiring a combination of corrosion resistance, thermal stability and useful mechanical performance.
Important characteristics include:
- Strong corrosion resistance
- Good resistance to localized corrosion
- Resistance to many aggressive chemical environments
- Good thermal stability
- Good welding characteristics
- Useful ductility
- Good fabrication capability
- Nickel-based alloy construction
- Availability in rod and bar forms
Haynes specifically notes that HASTELLOY C-4 has good resistance to stress-corrosion cracking and good resistance to general corrosion and chloride-induced pitting and crevice attack.
Corrosion Resistance of Hastelloy C4
One of the main reasons engineers specify Hastelloy C4 is its corrosion performance in demanding chemical environments.
Industrial equipment may be exposed to:
- Acidic process chemicals
- Chloride-containing environments
- High-temperature process streams
- Oxidizing conditions
- Reducing conditions
- Wet chemical environments
- Aggressive process media
Hastelloy C4 is engineered for corrosion-resistant service and can be considered when material degradation is a major design concern.
However, no alloy should be selected only from a generic corrosion-resistance statement. Actual material selection should consider:
- Chemical concentration
- Operating temperature
- Pressure
- Exposure time
- Flow conditions
- Contaminants
- Welding condition
- Required design life
A qualified materials engineer should confirm suitability for critical process conditions.
Hastelloy C4 Round Bar Applications
Hastelloy C4 Round Bar can be machined into shafts, pins, fasteners, components and other engineered parts.
Chemical Processing Equipment
Chemical-processing equipment can encounter aggressive media and elevated operating temperatures.
Hastelloy C4 can be considered for selected:
- Reactor components
- Process equipment
- Valves
- Pump components
- Shafts
- Fasteners
- Machined parts
Heat-Resistant Components
C4 is also relevant where corrosion resistance must be maintained under elevated-temperature service.
Petrochemical Equipment
Selected petrochemical components may require nickel alloys when the process environment creates demanding corrosion conditions.
Pollution-Control Equipment
Corrosive gases and chemical process streams can create challenging operating environments. Specialty nickel alloys can be considered for selected components.
Chemical Storage and Handling
Components exposed to aggressive chemical environments may require corrosion-resistant alloy construction.
Industrial Machined Components
Round bar is particularly useful when the final component must be machined to a specified diameter, geometry or tolerance.
ASTM B574 Specification for Hastelloy C4
When purchasing Hastelloy C4 Round Bar, specifying the applicable ASTM standard helps create a clear technical requirement.
ASTM B574 covers low-carbon nickel-chromium-molybdenum and related nickel alloys for rod and bar applications. Its scope includes UNS N06455.
Haynes International also lists SB 574 / B 574 for HASTELLOY C-4 billet, rod and bar.
A typical procurement description can therefore be written as:
Hastelloy C4 Round Bar – Alloy C-4 – UNS N06455 – ASTM B574
Additional requirements can include:
- Diameter
- Length
- Heat treatment
- Surface finish
- Quantity
- Testing
- Inspection
- Material Test Certificate
Hastelloy C4 for High-Temperature Service
Hastelloy C4 is not simply a corrosion-resistant material; its performance at elevated temperature is also an important consideration.
Haynes notes that cold working can influence stress-corrosion-cracking resistance and recommends appropriate re-annealing considerations for sufficiently cold-worked components when optimum corrosion performance is required.
This makes processing history important for engineering applications.
When ordering C4 Round Bar for a critical application, buyers should communicate the intended service conditions rather than specifying only the alloy name.
A useful enquiry should mention:
Material + Standard + Size + Condition + Quantity + Application
This gives the supplier a better understanding of the requirement.
How to Buy Hastelloy C4 Round Bar
When searching online for a Hastelloy C4 Round Bar Supplier India, buyers should look beyond the material name and provide a complete technical specification.
