The HuaNickel UNS N08367 alloy is a super austenitic stainless steel containing 6% molybdenum, which is enhanced by its nitrogen content. The high nickel content of alloy 25-6HN makes it thermally stable and resistant to stress corrosion cracking, and alloy 25-6HN has significantly improved strength and corrosion resistance in most environments.

HuaNickel UNS N08811 is a nickel-iron-chromium superalloy, which has high-temperature strength and the ability to resist oxidation and high-temperature corrosion. Its high nickel content gives it excellent resistance to stress corrosion cracking in aqueous corrosion conditions. The high chromium content makes it more resistant to pitting corrosion and crevice corrosion cracking. The alloy has good corrosion resistance to nitric acid and organic acids, but has limited corrosion resistance in sulfuric acid and hydrochloric acid. In addition to the possibility of pitting corrosion in halides, there is good corrosion resistance in both oxidizing and non-oxidizing salts.

HuaNickel UNS N09901 is a Fe-Ni-Cr-based precipitation-hardened deformed superalloy. The alloy is aged strengthened with a metastable γNi₃(Ti,Al) phase, and a trace amount of aluminum inhibits the conversion of γ’ to ηNi₃Ti phase. The alloy has high yield strength and lasting strength below 650 °C, good oxidation resistance below 760 °C, and stable structure for long-term use.

HuaNickel UNS S33400 is an austenitic stainless steel containing titanium and aluminum, which has good high temperature stability and corrosion resistance. UNS S33400 is used in heating tubes, heat exchangers, equipment heaters, industrial furnaces and other equipment.
