Hastelloy's heat-resistant stainless steel was developed by Haynes International specifically for the needs of the chemical and aerospace industries. It was necessary to obtain a steel alloy that would be distinguished by such parameters as:
， The highest strength;
， Resistance to corrosion of all types;
， Resistance to deformation;
， Preservation of properties in a wide range of temperatures and pressures.
Hastelloy alloys, the price of which depends on the variety (there are about three dozen different types of this brand), include components such as nickel, chromium, manganese, iron, vanadium, cobalt, niobium, molybdenum, aluminum, etc.
Features and Applications
The main purpose of the alloys of this brand is to ensure the working process at high temperatures and pressures, as well as in acidic and alkaline atmospheres. Conventional stainless alloys generally do not have high durability under these conditions.
Hastelloy is most effective in this regard: it is used in the production of parts for nuclear reactors, in the manufacture of pipelines for transporting chemically active working media. In addition, they can be used as spraying on already existing structural elements and mechanisms to improve their performance (gas-thermal method).
