Heat resistant nickel-based alloys

Heat-resistant steels

The unparalleled properties of nickel-based heat resistant alloys are one of the main reasons for their successful use in various fields of human activity. Mainly, we are talking about such indicators as:

-Resistance to creep at high temperatures;

-thermal stability;

-durable strength (in some cases fatigue strength can be considered).

Nickel-based alloys provide such qualities not only through heat treatment, but also through multicomponent alloying. Highly alloyed steel contains more than 10% of alloying elements. For example 20X20H14C2 steel contains 12-15% nickel and 19-22% chromium. Manganese up to 1.5%, copper 0.3%, silicon 2-3%, carbon and titanium 0.2%, sulfur and phosphorus in the thousandth percentile are added to the blend as additives.

Heat-resistant structural alloys

Jet technology would not be possible without the special heat resistant alloys Inconel, Hastelloy. Transport engineering is based on the use of such high-strength nickel alloys. Chemical reactors, tanks, boilers and crucibles with high corrosion resistance are made of such alloys. Nickel-alloyed materials play a critical role in the construction of gas turbine engines and nuclear boilers. They are used as high-temperature protective cladding to protect uranium rods from corrosion in nuclear reactors.

All stainless steels contain nickel in their composition because it not only increases chemical resistance, but also gives the alloys toughness and strength.
