Hastelloy N / UNS N10003
Hastelloy is one of the most demanded steels in the world. More precisely, this is a whole line or group of alloys that was first developed and patented by a world-famous manufacturer – the Haynes company.
There are various types of steels (there are currently about thirty) , which differ in their composition and scope. It should be noted that each alloy is based on nickel and chromium, which give the material the highest strength and resistance to corrosion processes.
Varieties of steel can have different mass fractions of elements such as molybdenum, cobalt , carbon, copper, titanium, manganese, aluminum. Depending on the purpose and future scope of use, it is necessary to choose one or another steel grade
Features
Like any nickel alloy, Hastelloy has highest resistance to wear, corrosion and deformation. Along with Incoloy class alloys, this type is considered one of the most reliable and durable in operation in the most severe temperature and load conditions.
Corrosion-resistant alloys of this grade were specially created for the needs of the aerospace and chemical industries . Their main function is to ensure the operation of equipment at maximum temperatures in the presence of aggressive substances in the atmosphere.
