Chemically nearly identical to 6-molybdenum alloys AL6XN and SMO 254, alloy 926 is commonly used in paper mills, desalination and mild acid environments.
Inconel 718 Nuts, also known as Alloy 718, are a precipitation hardening (also known as age hardening) form of Inconel 625. This heating and quenching process is used to change the atomic structure of the alloy, making it stronger by locking the metal’s grain structure in place. Additional strength can be obtained by cold working.
Gold 926 fasteners are also similar in composition to 904L, but with the addition of nitrogen and molybdenum, resulting in alloy 926 bolts with improved general corrosion resistance as well as pitting and crevice corrosion resistance. Because Alloy 926 is resistant to chloride stress corrosion cracking, it makes 926 fasteners ideal for desalination, pulp and paper mills. This alloy is also ideal for dilute sulfuric and phosphoric acid applications.
Inconel 718 nuts have excellent resistance to chloride ion stress corrosion cracking due to their nickel-chromium content. Nickel in Alloy 718 helps to resist the alkalinity of many inorganic and organic compounds over a wide range of acidity and acidity, with the exception of strongly oxidizing compounds. Its chromium content makes it resistant to sulfur compounds and mild oxidizing media, while molybdenum helps prevent pitting.
