Incoloy MA956 , 圆棒，棒材，圆钢，锻件详细介绍

INCOLOY? alloy MA956 (UNS S67956), first developed as an aerospace superalloy and now used in a range of industrial applications, combines excellent strength and fabricability with outstanding resistance to prolonged exposure up to 1300°C (2400°F). Its exceptional properties result from the mechanical alloying process by which it is made; a process which allows a fine distribution of yttrium oxide particles to be incorporated into a highly corrosion-resistant Fe-Cr-Al alloy. The alloy has excellent oxidation resistance up to 1300°C (2400°F) and significant creep strength up to itsunusually high melting point of 1482°C (2700°F). Thicker sections may be used up to 1370°C (2500°F). Typical industrial applications include hearth rollers, radiant tubes, furnace muffles, fluidized bed retorts, heat treatment baskets, mesh belts, heat shields, burner nozzles, sensor tubes for thermowells and combustion chamber components for diesel engines. A full range of both hot and cold-worked mill products is available. The forming and machining characteristics are similar to those of conventional highchromium ferritic steels and Fe-Cr-Al alloys. Table 1.

(0.262 lb/in?) The unusually high solidus is 100-200°C higher than for most high-temperature nickel-base superalloys. Even at these extremely high temperatures the dispersion of yttrium oxide provides dimensional and structural stability and prevents embrittlement due to grain growth. The low density is only 70% that of molybdenum allowing INCOLOY alloy MA956 to be economicallysubstituted for similar size fixtures in vacuum furnaces. The lower mass also reduces loading stresses. Unlike molybdenum, the alloy is completely immune to accidental exposure to air at elevated temperatures. *Reference to the ‘balance’ of an alloy’s composition does not guarantee this is exclusively of the element mentioned, but that it predominates and others are present only in minimal quantities.
