What is Nickel Alloy

The Origin and Development of Nickel Alloy

Nickel Alloy traces its roots to the late 19th century when nickel’s corrosion resistance piqued industrial interest. 1905 Albert Marsh blended nickel with chromium, creating Nichrome—a heat-resistant nickel alloy. The 1920s brought Hastelloy, followed by Inconel and Monel in the mid-20th century, driven by aerospace and marine demands. Today, nickel-based superalloys like Inconel 718 power cutting-edge applications, building on a century of metallurgical innovation.

Standards, Grades, and Classifications

Nickel Alloy meets standards like ASTM B443 (Inconel 625) and ASTM B574 (Hastelloy C276), covering forms from sheets to pipes. Grades vary by purpose: Monel 400 for seawater, Incoloy 825 for acids, and nickel superalloy grades like Hastelloy X for heat. Classifications hinge on nickel content and alloying elements, shaping ni alloys into corrosion or high-strength specialists.

Chemical Elements and Proportions

Nickel Alloy relies on nickel (30-70%) as its base, paired with chromium (15-30%) for oxidation resistance, molybdenum (5-20%) for acid resistance, and iron or copper for strength. For example, Inconel 625 has ~60% nickel, 20% chromium, and 9% molybdenum, while Monel 400 blends 67% nickel with 23% copper.

Nickel Alloy drives performance across industries.

Limitations: What to Watch Out For

Despite its strengths, Nickel Alloy isn’t flawless:

  • High Temps: Nickel Alloy weakens above 982°C.
  • Oxidizing Acids: Less effective in nitric-rich settings.
  • Cost: High nickel alloys are pricier than stainless.
  • Work-Hardening: Rapid hardening complicates machining.

Corrosion Data: Resistance and Influencing Factors

Nickel Alloy resists corrosion effectively:

  • 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. Temperature and concentration influence rates—Incoloy 825 excels in acids.

Welding and Manufacturing

Welding Nickel Alloy requires precision:

  • Welding: TIG/MIG with ERNiCrMo-3 for Hastelloy; control heat to avoid cracking.
  • Forging: Heat to 870-1180°C for Inconel; air cool.
  • Machining: Sharp tools, low speeds—Nickel Alloy hardens quickly.

These techniques preserve Nickel alloy properties.
