Heat resisting steels and alloys
The main properties that characterize high-temperature stamps from other alloys is its high resistance to creep and prolonged strength. These qualities show how long products are able to work in conditions of exposure to elevated temperatures. The most common in use — heat-resistant steel, where the main element functions chrome. Also heat-resistant steel varies according to the type of hardening, the method of doping, the number of elements. In the segment of high-temperature. hire the company «Auremo» — the best supplier.
The Nickel-based alloys get increased resistance is not only due to multicomponent alloying with subsequent heat treatment. High alloy steel contain more than 10% of alloying elements. For example, the alloy grade 20KH20N14S2 is composed of Nickel 12−15%, chromium 19 to 22%. As additives to the mixture is added manganese up to 1.5%, copper — 0.3%, silicon — 2−3%, carbon and titanium 0.2%, sulfur and phosphorus — thousandths.
High-temperature grade 20KH25N20S2 relates to high-alloyed alloys based on iron, is smelted in an induction furnace.

Stainless steel heat-resistant grade 12h25n16g7ar is composed of Nickel 15 to 18% chromium 23−26%.

Unmatched properties of high-temperature alloys have become one of the main reasons for their successful application in various fields of human activity. The jet technique would be impossible without special heat-resistant alloys required for the creation of gas turbine engines… of Modern transport engineering is impossible to imagine without such high-strength alloys. Of these alloys produce chemical reactors, tanks, boilers and crucibles with high resistance to corrosion. Heat-resistant materials play a crucial role not only in the designs of gas turbine engines, but also in the construction of nuclear boilers. Heat resistant sheath is used for protection of uranium rods from corrosion in nuclear reactors.
