October 2018: New Chapter on 9Cr-1Mo added to ASMD, HPAD and AHAD
9Cr-1Mo is primarily used in applications where creep and corrosion resistance are needed. The chapter covers three grades of the alloy: Grade 9 (initial grade), Grade 91 (added Nb and V to improve creep resistance), and Grade 911 (added Nb, V, and W). It is used in nuclear applications and in the refining industry for high pressure and temperature piping, vessels, fittings, and turbines.

October 2018: New Chapter on Hastelloy G-35 added to HPAD and AHAD
G-35 alloy is a solid-solution strengthened, corrosion-resistant nickel-based alloy that was developed for the chemical industry, particularly in acid and chloride environments. The alloy is much less susceptible to chloride-induced stress corrosion cracking than stainless steels and nickel-chromium-iron alloys traditionally used in these applications.
