1. What is UNS N06985?

UNS N06985, or Hastelloy G-3, is a nickel-chromium-iron-molybdenum-copper alloy with approximately 44% nickel, 22% chromium, 7% molybdenum, and 2% copper, designed for superior resistance to phosphoric and sulfuric acids, as well as intergranular corrosion in welded conditions. Its low carbon content minimizes sensitization, making UNS N06985 material ideal for flue gas scrubbers, acid production, and chemical processing equipment. Compared to UNS N08825, UNS N06985 offers enhanced weldability and resistance to reducing acids.

Gangsteel’s UNS N06985 alloy steel plate is tailored for aggressive chemical environments, providing a robust alternative to nickel alloy steel grades like UNS N06030 and UNS N06200.
