When discussing advanced metal alloys used in demanding industries such as aerospace, chemical processing, and nuclear reactors, one name that frequently surfaces is Hastelloy. Known for its exceptional corrosion resistance and superior strength at high temperatures, Hastelloy has earned a reputation as a premium material choice in many critical applications.
However, those new to the field or exploring alternatives might wonder, what’s another name for Hastelloy or if there are any equivalent materials they should consider. The truth is, Hastelloy is actually a trademarked name for a family of corrosion-resistant metal alloys primarily composed of nickel, with varying amounts of molybdenum, iron, and other elements.
These alloys come in different grades and compositions, each tailored for specific applications.
Understanding Hastelloy’s alternative names or comparable materials is crucial for engineers, purchasing agents, and metallurgists who need to make informed decisions about material selection. This post delves deep into what Hastelloy is also known as, explores its related alloys, and explains the significance behind its various designations.
From trademark names to generic equivalents, you’ll find a detailed exploration of Hastelloy’s identity and its place within the broader world of superalloys.
Understanding Hastelloy: The Basics
Before we dive into alternative names for Hastelloy, it’s important to grasp what Hastelloy really is. This alloy family is primarily nickel-based, but it also includes elements like molybdenum and iron that enhance its corrosion resistance and mechanical properties.
Hastelloy was originally developed by the Haynes International company, and it quickly became popular for applications where resistance to oxidation, pitting, and crevice corrosion is vital. The name “Hastelloy” itself is a registered trademark, which means it’s a brand rather than a generic term for any nickel alloy.
The alloy’s composition varies depending on the grade or type—such as Hastelloy C-22 or Hastelloy B-2—each designed to withstand different chemical environments or temperature ranges.
“Hastelloy alloys are indispensable in harsh chemical processes due to their unmatched corrosion resistance.” – Metallurgical Review Journal
Key Characteristics of Hastelloy
- Corrosion resistance: Excellent resistance to oxidizing and reducing agents.
- High-temperature strength: Maintains structural integrity in extreme heat.
- Versatility: Various grades suited for a wide range of environments.
- Cost: Typically more expensive than stainless steel but justified by performance.
Trademark vs. Generic Names: What’s Another Name for Hastelloy?
Since “Hastelloy” is a trademark, the question of “what’s another name for Hastelloy” often leads us to generic or equivalent names used in the industry. While no exact synonym exists due to legal restrictions, several nickel-based alloys share similar compositions and properties.
Industry professionals often refer to these nickel alloys by their UNS (Unified Numbering System) designations or by alternative brand names that resemble Hastelloy’s functionality.
For example, some people might refer to Hastelloy as “nickel-molybdenum alloy” or “nickel-based superalloy” to describe its general category without infringing on trademarks.
Common Generic Names and Equivalents
- Nickel-Molybdenum Alloys: A broad class that includes Hastelloy variants.
- Inconel: Another family of nickel-chromium-based superalloys often compared to Hastelloy.
- Monel: A nickel-copper alloy with overlapping usage but different corrosion profiles.
- Alloy B-2: Refers specifically to a grade of Hastelloy but sometimes used generically.
| Brand Name | Generic Equivalent | Primary Elements | Common Use |
| Hastelloy | Nickel-Molybdenum Alloy | Nickel, Molybdenum, Iron | Chemical processing, reactors |
| Inconel | Nickel-Chromium Alloy | Nickel, Chromium, Iron | High-temperature aerospace |
| Monel | Nickel-Copper Alloy | Nickel, Copper | Marine applications |
Exploring Different Grades of Hastelloy and Their Names
Hastelloy is not a single alloy but a family of grades, each with its own chemical makeup and performance traits. Understanding these grades helps clarify what people might mean when they look for “another name for Hastelloy.”
Some of the most common grades include Hastelloy B-2, C-22, and C-276. Each grade targets specific corrosion resistance needs, from hydrochloric acid environments to strong oxidizers.
Hastelloy B-2
This grade is known for its excellent resistance to hydrochloric acid and reducing environments. It contains high nickel and molybdenum with low iron, making it highly resistant to pitting and stress corrosion cracking.
Because of its unique characteristics, sometimes it’s referred to simply as “Alloy B” or “B-2 alloy” in technical documents, which might confuse newcomers searching for equivalent names.
Hastelloy C-22 and C-276
Both C-22 and C-276 are versatile grades designed for oxidizing and reducing conditions. C-22 includes higher chromium content for improved resistance to oxidizers, while C-276 is a balanced alloy that handles a broad spectrum of aggressive chemicals.
In industry jargon, these may be called “Alloy C” or referred to by their UNS numbers (e.g., UNS N06022 for C-22 and UNS N10276 for C-276).
- Hastelloy B-2: Also known as Alloy B or UNS N10665.
- Hastelloy C-22: Sometimes called Alloy C or UNS N06022.
- Hastelloy C-276: Known as Alloy C-276 or UNS N10276.
Comparing Hastelloy with Other Nickel-Based Alloys
It’s common to compare Hastelloy with other nickel alloys, especially Inconel and Monel, to understand their differences and overlaps. While these alloys share nickel as a base, their additional elements and properties vary.
This comparison is critical when choosing materials for specific environments. For example, Hastelloy’s superior resistance to strong acids often makes it preferable in chemical plants, whereas Inconel’s high-temperature strength suits jet engines.
| Alloy | Key Elements | Corrosion Resistance | Typical Applications |
| Hastelloy | Nickel, Molybdenum, Iron, Chromium | Excellent in acids | Chemical reactors, heat exchangers |
| Inconel | Nickel, Chromium, Iron | Oxidation and high-temp corrosion | Aerospace turbines, exhaust systems |
| Monel | Nickel, Copper | Good in seawater and alkalis | Marine equipment, valves |

Historical and Trademark Perspectives on the Name “Hastelloy”
Hastelloy’s origin dates back to the early 20th century when Haynes International developed it as a proprietary material for extreme environments. Over time, the name became synonymous with high-performance nickel alloys, but it remains a registered trademark.
This trademark status means that while many alloys share similar compositions, only Haynes International’s products can officially be called Hastelloy. This distinction drives the use of alternative names or UNS numbers in technical and commercial contexts.
Many suppliers offer nickel-molybdenum alloys similar to Hastelloy under their own brand names, sometimes leading to confusion about the alloys’ true identity.
Trademark Implications
- “Hastelloy” is a brand owned by Haynes International.
- Other manufacturers produce equivalents but use different names.
- UNS numbers provide a universal identification system.
- Understanding trademarks helps avoid mislabeling in procurement.
