What is Nickel Based Alloy
The Origin and Development of Nickel Based Alloy
Nickel Alloys trace their roots to the late 19th century when nickel’s durability sparked industrial curiosity. In 1905, Albert Marsh’s Nichrome—a nickel alloy blending nickel and chromium—kicked off the era of heat-resistant metals. The 1920s saw Haynes International unveil Hastelloy, a nickel-based Alloy tackling acid corrosion. Inconel and Monel followed in the mid-20th century for aerospace and marine needs. Today, nickel-based superalloys like Inconel 718 and Hastelloy C276 lead cutting-edge applications fueled by decades of metallurgical progress.
Standards, Grades, and Classifications
Nickel-based Alloys adhere to standards like ASTM B443 (Inconel 625) and ASTM B574 (Hastelloy C276), covering forms from bars to sheets. Grades are split by purpose: Monel 400 for saltwater, Incoloy 825 for acids, and nickel superalloys like Hastelloy X for heat. Classifications depend on nickel content and alloying elements, shaping nickel alloys into corrosion or strength specialists.
Chemical Elements and Proportions
Nickel Based Alloys hinge on nickel (30-70%), with chromium (15-30%) boosting oxidation resistance, molybdenum (5-20%) fighting acids, and iron or copper adding strength. For example, Inconel 625 packs ~60% nickel, 20% chromium, and 9% molybdenum, while Monel 400 blends 67% nickel with 23% copper.

Types of Nickel Based Alloy
| Type | Key Composition | Characteristics | Common Grades |
|---|---|---|---|
| Monel | Ni (65-70%), Cu (20-30%) | Seawater corrosion resistance | Monel 400, K-500 |
| Inconel | Ni (50-70%), Cr (15-25%) | High-temp strength, oxidation | Inconel 625, 718 |
| Incoloy | Ni (30-45%), Fe (20-40%) | Acid resistance, thermal stability | Incoloy 825, 800 |
| Hastelloy | Ni (50-60%), Mo (15-30%) | Extreme corrosion resistance | Hastelloy C276, C22 |
Chemical Properties: Behavior in Different Environments
Nickel Based Alloys tackle tough chemical challenges effortlessly.
| Property | Behavior | Key Elements | Notes |
|---|---|---|---|
| Corrosion Resistance | Excels in acids, saltwater | Ni, Mo, Cr | Hastelloy shines in HCl |
| Oxidation Resistance | Stable up to 982°C | Cr, Fe | Inconel for heat |
| Magnetism | Mostly non-magnetic | Ni dominance | Monel may vary |
| Heat Resistance | Reliable to 538-1200°C | Mo, Ni | Grade-specific |
Physical Properties: Strength, Hardness, and Ductility
Nickel Based Alloys outmuscle stainless while staying formable.
| Material | Tensile Strength (MPa) | Hardness (HB) | Elongation (%) | Notes |
|---|---|---|---|---|
| Inconel 625 | 827 - 1034 | ≤ 290 | ≥ 30 | Beats SS in strength |
| Hastelloy C276 | 690 - 930 | ≤ 220 | ≥ 40 | Superior corrosion edge |
| 316 Stainless | 515 - 690 | ≤ 217 | ≥ 40 | Weaker in harsh settings |
| Titanium Gr 5 | 900 - 1000 | 334 | ≥ 10 | Strong, less ductile |
Applications: Industries and Uses
Nickel Based Alloys shines across industries:
- Aerospace: Inconel 718 in jet engines for heat endurance.
- Chemical: Hastelloy C276 in acid-rich reactors.
- Marine: Monel 400 in seawater pumps.
- Oil & Gas: Incoloy 825 in sour gas wells.
- Power: nickel based superalloys in turbines.
Nickel Based Alloys thrive in extreme conditions.
Limitations: What to Watch Out For
Despite its strengths, Nickel Based Alloys isn’t flawless:
- Heat Limits: Nickel Based Alloys falter above 982°C.
- Oxidizing Acids: Struggle with nitric-rich environments.
- Cost: High nickel alloys outprice stainless.
- Machining: Work-hardening demands precision.
Corrosion Data: Resistance and Influencing Factors
Nickel Based Alloys resist corrosion well:
- 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. Factors like temp and concentration matter—Incoloy 825 excels in acids.
Welding and Manufacturing
Welding Nickel Based Alloy requires precision:
- Welding: TIG/MIG with ERNiCrMo-3 for Hastelloy; keep heat low.
- Forging: 870-1180°C for Inconel; air cool.
- Machining: Sharp tools, slow speeds—Nickel Based Alloys harden fast.
These steps preserve nickel alloy properties.
