Corrosion-resistant
The INCOLOY® 800 series of alloys, invented by the
Special Metals Corporation Group of Companies, is the
result of years of monitoring and maintaining the
ultimate chemical properties for high-temperature
strength and resistance to oxidation, carburization and
other types of high-temperature corrosion.
Each one a refinement of the one before, these
alloys have set the industry standard in hightemperature
applications requiring optimum creep and
rupture properties.
INCOLOY nickel-iron-chromium alloy 800 was
introduced to the market in the 1950s to fill the need for
a heat- and corrosion-resistant alloy with a relatively
low nickel content since nickel was, at the time,
designated a “strategic” metal. Over the past forty years
it has been widely used for its strength at high
temperatures and its ability to resist oxidation,
carburization, and other types of high-temperature
corrosion. Applications include furnace components
and equipment, petrochemical furnace cracker tubes,
pigtails and headers, and sheathing for electrical heating
elements.
In 1963, the alloy was approved by the ASME
Boiler and Pressure Vessel Committee, and the design
stresses were published in Code Case 1325. For the first
time, aluminum and titanium were listed as purposeful
additions (at 0.15 to 0.60% each), and annealed material
was differentiated from solution-annealed material. The
new terms “Grade 1, annealed at approximately 1800°F
(980°C)” and “Grade 2, annealed at approximately
2100°F (1150°C)” came into use. The Code Case
covered Sections I and VIII, and listed design stresses
for Grade 1 to 1100°F (593°C) and for Grade 2 to
1500°F (816°C).
