Quick Answer: What Is Incoloy 925? (60-80 words)

Incoloy 925 (UNS N09925 / W.Nr. 2.4852) is a precipitation-hardenable nickel-iron-chromium alloy that combines the high strength of a precipitation-hardened alloy with the excellent corrosion resistance of Incoloy 825. It is specifically designed for high-stress applications in aggressive sour gas environments containing hydrogen sulfide, chlorides, and carbon dioxide. Its unique chemistry provides outstanding resistance to pitting, crevice corrosion, and stress-corrosion cracking (SCC).

Product Overview (150 words)

Incoloy 925 (UNS N09925) is a high-performance member of the nickel-iron-chromium alloy family. Strengthened by additions of titanium and aluminum through a specific age-hardening heat treatment, it offers roughly twice the yield strength of non-hardened alloys while maintaining exceptional chemical stability. Its primary properties include superior resistance to sulfide stress cracking and polythionic acid stress-corrosion cracking, making it a "gold standard" for the Oil & Gas, Chemical Processing, and Marine Engineering industries.

Founded in 2012, Shanghai Hangbo Alloy Group Co., Ltd. has established itself as a premier manufacturer and technical partner for special metals.
