1. What is UNS N08825?

UNS N08825is a nickel-chromium-molybdenum-copper superalloy with nickel (38.0-46.0%), chromium (19.5-23.5%), molybdenum (2.5-3.5%), and copper (1.5-3.0%), designed for superior resistance to sulfuric and phosphoric acids, pitting, and stress-corrosion cracking (SCC). Stabilized with titanium to prevent intergranular corrosion, UNS N08825 material is ideal for oil and gas pipelines, chemical reactors, and marine equipment. Compared to UNS N08020, UNS N08825 offers enhanced resistance in oil/gas environments due to higher nickel content.

Gangsteel’s UNS N08825 alloy steel plate is tailored for aggressive chemical and marine applications, providing a robust alternative to nickel alloy steel gradeslike UNS N10675and UNS N06985.
