1. What is UNS N06625?

 

UNS N06625, or Inconel 625, is a nickel-based superalloy with high nickel (58% min), chromium (20.0-23.0%), and molybdenum (8.0-10.0%), enhanced by niobium (3.15-4.15%) for solid-solution strengthening. This composition provides outstanding resistance to pitting, crevice corrosion, and oxidation, making UNS N06625 alloy steel plate ideal for harsh environments like seawater, acidic conditions, and high-temperature systems. Compared to UNS N06617, UNS N06625 offers superior corrosion resistance in chloride-rich environments.

Gangsteel’s UNS N06625 is tailored for demanding applications, providing a versatile alternative to nickel alloy steel gradeslike UNS N07214and Alloy C276.
