SULFIDATION/OXIDATION RESISTANT ALLOY

摘要

A nickel-base alloy is disclosed containing (in weight percent) Chromium 25-35 Aluminium 2-5 Iron 2.5-6 Niobium 0-2.5 Carbon 0-0.1 Nitrogen 0-0.05 Titanium 0-1 Zirconium 0-1 Boron 0-0.01 Cerium 0-0.05 Yttrium 0-0.05 Silicon 0-1 Manganese 0-1 Nickel Rest The alloy affords a high degree of resistance to sulphidation and oxidation at elevated temperatures and is suitable for use in glass vitrification furnaces.
