What is Hastelloy
The Origins and Evolution of Hastelloy
Hastelloy began in the early 20th century with Haynes International, founded by Elwood Haynes. In 1920, Haynes patented the first Hastelloy alloy, blending nickel with molybdenum to combat corrosion from hydrochloric acid—a breakthrough for chemical processing. Over decades, Hastelloy evolved into a family of superalloys, with grades like Hastelloy C (1930s) and Hastelloy C276 (1960s) refining weldability and resistance. Today, Hastelloy stands as a pinnacle of Corrosion Resistant Alloys, driven by relentless innovation.
Standards, Grades, and Classifications
Hastelloy alloys adhere to standards like ASTM B574 (bars) and ASME SB-575 (plates), with grades classified by composition and purpose. Key Hastelloy grades include Hastelloy C276, Hastelloy C22, Hastelloy C2000, and Hastelloy B-3, each optimized for specific environments—think High Temperature Alloys for aerospace or Corrosion Resistant Alloys for acids.
Chemical Elements and Proportions
Hastelloy is a nickel-based superalloy, typically with nickel (50-70%), chromium (15-23%), and molybdenum (5-30%). Additions like iron, tungsten, or copper tweak its properties. For example, Hastelloy C276 boasts 16% molybdenum for acid resistance, while Hastelloy X includes iron for heat strength.
Hastelloy Characteristics
Types of Hastelloy
| Type | Composition (Key Elements) | Characteristics | Common Grades |
|---|---|---|---|
| B-Series | Ni (65%), Mo (28-30%) | High resistance to reducing acids | B-2, B-3 |
| C-Series | Ni (50-60%), Cr (15-22%), Mo (13-16%) | Versatile corrosion resistance | Hastelloy C276, C22, C2000 |
| G-Series | Ni (40-45%), Cr (22-30%), W | Phosphoric acid resistance | G-30, G-35 |
| X-Series | Ni (44%), Cr (22%), Fe (20%) | High-temp strength, oxidation | Hastelloy X |
Chemical Properties: Behavior in Different Environments
Hastelloy shines where others fail—think Hastelloy C276 in wet chlorine or Hastelloy C22 in mixed acids.
| Property | Behavior | Key Elements | Notes |
|---|---|---|---|
| Corrosion Resistance | Exceptional in acids (HCl, H2SO4) | Ni, Mo, Cr | Strong in reducing/oxidizing media |
| Oxidation Resistance | Stable up to 1200°C (2200°F) | Cr, Fe | Ideal for High Temperature Alloys |
| Magnetism | Non-magnetic | Ni dominance | Useful in sensitive equipment |
| Heat Resistance | Good to 538-982°C (1000-1800°F) | Mo, W | Varies by grade |
Physical Properties: Strength, Hardness, and Ductility
Compared to stainless, Hastelloy offers unmatched corrosion resistance alongside robust strength.
| Property | Hastelloy (C276) | Stainless Steel (316) | Notes |
|---|---|---|---|
| Tensile Strength | 690-930 MPa | 515-690 MPa | Hastelloy outshines in stress |
| Yield Strength | ≥ 310 MPa | ≥ 205 MPa | Superior load-bearing capacity |
| Hardness (Brinell) | ≤ 220 HB | ≤ 217 HB | Comparable, but Hastelloy resists corrosion |
| Elongation | ≥ 40% | ≥ 40% | Excellent ductility for forming |
Applications: Industries and Uses
Hastelloy shines across industries:
- Chemical Processing: Hastelloy C276 in reactors handling sulfuric acid.
- Aerospace: Hastelloy X in turbine blades for heat resistance.
- Oil & Gas: Hastelloy C22 in sour gas wells.
- Marine: Hastelloy material for seawater pumps.
- Pharma: Hastelloy C2000 in sterile equipment.
Hastelloy uses span wherever durability meets corrosion.
Limitations: What to Watch Out For
Despite its strengths, Hastelloy isn’t flawless:
- Temperature Caps: Hastelloy weakens above 982°C (e.g., Hastelloy C276).
- Oxidizing Acids: Struggles with concentrated nitric acid.
- Cost: Hastelloy price is higher than stainless due to nickel and molybdenum.
- Work-Hardening: Rapid hardening during machining needs careful handling.
Corrosion Data: Resistance and Influencing Factors
Hastelloy excels in corrosive settings:
- Saltwater: < 0.05 mm/year (Hastelloy C276).
- Sulfuric Acid (10%): 0.1-0.2 mm/year.
- Nitric Acid (10%): 0.5-1.0 mm/year (moderate). Factors like temperature, concentration, and surface finish impact rates—Hastelloy C22 outperforms in chlorides.
Welding and Manufacturing
Welding Hastelloy requires precision:
- Welding: TIG/MIG with ERNiCrMo-3 filler for Hastelloy C276; no preheat needed.
- Forming: Hot-forge at 870-1180°C (1600-2150°F); anneal post-cold work.
- Machining: Use sharp tools, low speeds—Hastelloy work-hardens fast.
These ensure Hastelloy metal retains its properties.

Frequently Asked Questions
Q1: What makes Hastelloy different from Inconel?
A: Hastelloy (like Hastelloy C276) focuses on molybdenum for superior acid resistance, while Inconel leans on chromium for heat strength. Pick Hastelloy for corrosion, Inconel for high temps.
Q2: Which Hastelloy grade is best for chemical processing?
A: Hastelloy C276 is a star here—its c276 material resists hydrochloric and sulfuric acids like no other. Hastelloy C22 is great for mixed acids too.
Q3: How corrosion-resistant is Hastelloy compared to stainless steel?
A: Hastelloy outshines stainless hands down. For example, Hastelloy C276 shows <0.05 mm/year corrosion in saltwater vs. 0.5-1 mm/year for 316 stainless—perfect for Corrosion Resistant Alloys.
Q4: Can Hastelloy withstand high temperatures?
A: Yes, up to 982°C (1800°F) for grades like Hastelloy X—ideal as a High Temperature Alloy. Beyond that, strength dips, so check your grade’s limit.
Q5: Is Hastelloy weldable?
A: Definitely! Use TIG or MIG with ERNiCrMo-3 filler for Hastelloy C276 or C22—no preheat needed. It’s a fabricator’s dream Hastelloy metal.
Q6: What’s the toughest Hastelloy grade for acids?
A: Hastelloy C2000 takes the crown with its copper boost, tackling sulfuric and nitric acids better than most Hastelloy grades.
