1. What is UNS N08028?

UNS N08028is a high-alloy multi-purpose austenitic stainless steel with nickel (31-34%), chromium (26-28%), molybdenum (3-4%), and copper (0.6-1.4%), designed for excellent resistance to reducing and oxidizing acids, pitting, and stress-corrosion cracking (SCC). Its low carbon content minimizes sensitization, making UNS N08028 material ideal for welded structures in phosphoric and sulfuric acid environments. Compared to UNS N08825, UNS N08028 offers superior pitting resistance due to higher chromium and molybdenum.

Gangsteel’s UNS N08028 alloy steel plate is tailored for highly corrosive conditions, providing a robust alternative to nickel alloy steel grades like UNS N10675 and UNS N06030.
