| http://www.w3.org/ns/prov#value | - The casing 11 is preferably constructed of a high temperature metal in the target zone, where casing temperatures may be hotter than 1400??? F. Typical high temperature metals may be, for example, 304 or 304H stainless steel, INCOLOY 800H, MA 253, HAYNES HR-120, or other alloys selected for acceptable corrosion and creep resistance at high temperatures.
