Inconel 718 nickel alloy steel Description

Inconel 718 high-performance nickel-based steel renowned for its exceptional strength, corrosion resistance, and versatility in extreme environments. Inconel 718 nickel alloy steel widely used in aerospace, energy, and industrial applications, this alloy, often referred to as Inconel 718 superalloy, stands out for its ability to maintain mechanical integrity under high temperatures and harsh conditions.
Inconel 718 alloy steel under the ASTM B637 standard, it is a precipitation-hardened alloy designed for superior performance in demanding conditions. Its key properties include:

  • High-Temperature Strength: Retains strength up to 704°C (1300°F), ideal for Inconel 718 aerospace components.
  • Corrosion Resistance: Excellent resistance to oxidation, pitting, and stress-corrosion cracking in harsh environments like acidic or saline conditions.
  • Fatigue Resistance: Superior performance under cyclic loading, critical for rotating parts.
  • Weldability: Good weldability with resistance to post-weld cracking, unlike many other nickel alloys.
  • Creep Resistance: Maintains structural integrity under prolonged stress at elevated temperatures.
