The SIPREME brand includes superalloys and nickel alloys


SIPREME 800H is a nickel-iron-chromium superalloy that provides high strength and excellent resistance to oxidation and carburization at high temperatures. It has good resistance to many nitriding atmospheres. High creep resistance is attained through control over crystal grains via high temperature heat treatment, together with fine control over carbon, titanium, and aluminium content.


Nickel alloys of the SIPREME brand are used for industrial heating systems, for pipes in petrochemical furnaces, in the aviation and space industries, the hydrocarbon processing industry, and in electricity generation.
