Incoloy 800/800H/800HT Specification
Incoloy 800 is also known as Alloy 800. Its nickel-iron-chromium composition makes it useful in environments with temperatures up to 1100° F. Incoloy 800/H/HT are used in areas where resistance to corrosion and oxidation is crucial.
Incoloy 800H has the same composition as Alloy 800: a nickel-iron-chromium alloy. تاہم, Incoloy 800H has superior resistance to creep rupture compared to Alloy 800. The increased strength results from a high temperature anneal of carbon, aluminum and titanium added into the composition. The additions serve to increase Incoloy 800 H’s strength and temperature resistance, along with resistance to carbonization and oxidation.
Incoloy 800 HT has the same chemical makeup as Incoloy 800 H but for the differences in carbon, aluminum and titanium quantities. Incoloy 800 H has more carbon, but Incoloy 800 HT is composed of more aluminum and titanium. This gives 800 HT even greater resistance to high temperatures. Incoloy 800 H/HT are recommended for temperatures exceeding 1100° F, often in instances where stainless steels are subject to crack and creep. The Incoloy alloys are commonly used in high temperature environments, such as industrial furnaces, chemical and nuclear vessels, and heat-treating equipment. Both Incoloy 800 H and 800 HT are dually certified.

سنکنرن مزاحمت
Incoloy 800/800H/800HT is generally free from both chloride stress corrosion cracking and intergranular corrosion caused by sensitisation. The alloy can be used in sea water. Incoloy 800/800H/800HT has resistance to acids similar to austenitic stainless steels. It has excellent resistance to both oxidising and non oxidising salts, except for halide salts, where pitting may occur. Please consult Austral Wright Metals for advice on your specific application.
گرمی کا علاج
The grade has high rate of work hardening. Hence, after cold working to remove brittleness, the grade needs to annealed. Annealing is done by heating the grade about 980°C for about 15 minutes, and then air cooling.
گرم کام کرنا
INCOLOY alloy 800 can be hot worked at temperature ranges of 871-1232°C (1600-2250°F).
ٹھنڈا کام کرنا
Cold working may be done on the alloy using standard tooling.
مشینی صلاحیت
Incoloy 800/800H/800HT are “C” class alloys, difficult to machine. Heavy machines, sharps, slow speeds and deep cuts to remove the work hardened layer are needed.
ویلڈنگ
The grade can be readily welded by common welding techniques like gas tungsten arc welding, shielded metal arc welding, metal inert gas welding, وغیرہ. Post-weld annealing might not be required. The grade can be appropriately brushed for impurities and heat tint is removed after welding.
من گھڑت
Incoloy 800/800H/800HT can be readily hot worked. Forging is finished above 870°C, and air cooled. The work is then solution annealed. The alloys can be cold formed similarly to stainless steel but deformation forces are higher.
