⚡ What is Monel 400 (Alloy 400)?

• Designation: UNS N04400 | W.Nr. 2.4360 / 2.4361

• Composition: ~67% Nickel, ~30% Copper with small additions of Fe, Mn, Si, and C.

• Properties:
  ✅ High strength across subzero to 538°C (1000°F)
  ✅ Excellent resistance to seawater, brackish water, steam, salts, and alkalis
  ✅ Superior performance in hydrochloric and hydrofluoric acids (de-aerated)
  ✅ Resistant to stress corrosion cracking and pitting in fresh and industrial waters
  ✅ Non-magnetic to slightly magnetic at room temperature

Monel 400 is work-hardenable only (not precipitation hardenable), making it ideal for marine, chemical, oil & gas, aerospace, defense, and power generation industries.
