UNS N06625 alloy steel plate, widely known as Inconel 625, is a nickel-chromium-molybdenum superalloy supplied by Gangsteel. Renowned for its exceptional corrosion resistance and high strength up to 1800°F (982°C), UNS N06625 material is ideal for aerospace, marine, and chemical processing applications.
As a leading stainless steel supplier in China, Gangsteel offers UNS N06625 plate, sheet, bar, and custom components, meeting ASTM B443, ASME SB-443, and AMS 5599 standards. This page details the UNS N06625 chemical composition, mechanical properties, equivalent materials, specifications, and applications, along with competitive UNS N06625 price per kg. Explore our nickel alloy steel gradesfor related alloys like UNS N06617, UNS N06002, and Alloy C276.
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.
