CORROSIVE-RESISTANT ALLOY Russian patent published in 2018 - IPC C22C19/05 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy, to the nickel-based alloys, which are intended for use in aggressive oxidizing environments. Corrosion-resistant alloy contains, wt%: carbon ≤0.006, silicon ≤0.1, manganese ≤1.0, chromium 22.8–24.0, iron ≤0.75, molybdenum 12.0–14.0, niobium 0.01–0.03, titanium 0.01–0.06, aluminum 0.1–0.2, magnesium 0.005–0.01, phosphorus ≤0.015, sulfur ≤0.012, nickel and inevitable impurities – the rest.

EFFECT: alloy is characterized by a high level of plastic properties during operation in the temperature range from 550 °C to 625 °C and by an increased resistance to corrosion cracking in molten chlorides KCl, AlCl₃+(ZrCl₄ HfCl₄), at the temperature up to 650 °C.
