1. What is UNS N10675?

UNS N10675is a nickel-molybdenum superalloy with high nickel (balance, ~65%) and molybdenum (27.0-32.0%), designed for superior corrosion resistance in aggressive reducing acid environments, such as hydrochloric, sulfuric, and acetic acids. Its low carbon content and optimized alloy composition enhance thermal stability and weldability, making UNS N10675 alloy steel plate ideal for chemical reactors, distillation columns, and acid production equipment. Compared to UNS N10276, UNS N10675 offers improved resistance to intergranular corrosion and stress-corrosion cracking (SCC) in reducing acids.

Gangsteel’s UNS N10675 is tailored for harsh chemical applications, providing a robust alternative to nickel alloy steel gradeslike UNS N06200and UNS N08020.
