Alloys have been around for a long time, Incoloy and Inconel are patented products of American superalloysis. Superior alloys are a precise blend of elements with careful treatment to ensure they can perform under some of the most extreme industrial conditions.
Incoloy is suitable for sulfuric acid of various concentrations at low temperature. It has good corrosion resistance in 50% - 70% caustic alkali (such as NaOH) solution and does not produce stress corrosion cracking. Inconel is suitable for various solutions and acids containing Cl -, as well as for many media such as caustic soda with concentration less than 70%.
Incoloy is a nickel chromium iron alloy designed for oxidation and carbonization at elevated temperatures. There are many kinds of Incoloy alloy: common ones such as Incoloy800, Incoloy800H, Incoloy800HT, Incoloy825, Incoloy840, Incoloy901, Incoloy925, Incoloy20, Incoloy330, Incoloy 25-6Mo etc.
Applications, where Inconel alloys are used, are as follows:
Chemical and petrochemical processing
Flare stacks on offshore oil platforms
Gas turbines, rocket motors/engines, and spacecraft
Pollution control equipment
Inconel is a nickel, iron, and cobalt based alloy developed for applications that generally require excellent mechanical and chemical properties at high temperatures. Inconel 718 is a kind of precipitation hardening nickel chromium alloy, Inconel 600's high nickel composition makes the alloy have very strong resistance to chloride stress fission corrosion, and can maintain its high corrosion resistance in reducing state and also have strong corrosion resistance in alkali solution. Inconel X-750 alloy is mainly a nickel base aging strengthened by γ "[Ni3 (al, Ti, Nb)] phase Superalloy; etc. Here are the characteristics of each steel grade
Grade of Inconel: Inconel 625: INCONEL alloy 625 has the most covetable blend of key properties, offering high strength, excellent fabricability and outstanding corrosion resistance.
INCONEL C-276: INCONEL alloy C-276 It is known for its outstanding corrosion resistance to both acid and alkali media, making it exceptionally useful in very inhospitable environments.
Applications, where Incoloy alloys are used, are as follows:
carburizing equipment, heating-element sheathing, process piping, heat exchangers, nuclear steam-generator tubing,
heat-treating equipment, chemical and petrochemical processing, power plants, industrial furnaces,
oil, and gas well piping, nuclear fuel reprocessing, acid production, pickling equipment.
