Stainless steel sheet of heat-resistant material HN77TYUR nickel-based — multifunctional material with exceptional features. It comes 0.5−12 mm thick. There are differences in precision rolling, the degree of stretching, the variety of surface treatment, cutting the size, nature of edge. Currently there is no single (global) symbol system rolled materials. Adopted settled alphanumeric designation.
1. The letters refer to the name of the main chemical elements (X — chrome, N — Nickel, T — titanium, Yu — aluminum), P — cerium contained in the alloy HN77TYUR, and ways of smelting (BT);
2. The digit indicates the average percentage of the basic elements, in this case — nickel alloy as the foundations — 77%.

Stainless steel sheet HN77TYUR relates to austenitic rolled metal materials with high corrosion resistance, heat resistance and heat resistance. The presence of chromium in the sheet material provides not only heat resistance but also chemical and corrosion resistance due to formation of a thin protective surface oxide film. Nickel-based stainless steel sheet material provides the necessary ductility and toughness. This simplifies the process of forming. It has high strength properties in all conditions, good resistance to organic acids, mineral acids and weak nitric acid. However, sulfuric acid and hydrochloric acid dissolved such sheet. It has a short-term strength limit of 930 MPa and a 20% elongation at break. Heat treatment involves quenching from 1080 to 1120 ° C, cooling in water.
The density of the sheet at 20 ° C is 8.2 g / cm³. first-order modulus of elasticity of 1.96 MPa and temperature (linear) expansion coefficient of 16.8 1 / deg at a temperature of 100 ° C. Coefficient of thermal conductivity (13.9 — 31.1 W / (m • deg) in the temperature range 100 — 900 ° C). The finished sheet may be subjected to various kinds of processing while preserving its basic properties and aesthetic appearance. Compared to a black metal sheet provides the most meaningful elements of strength, lightness, durability, easy maintenance. The disadvantages of the sheet include its high cost. However, considering the possibility of long-term use without special care, the use of the sheet is more economical compared to other materials.

Aerospace, machine building, petrochemical, medical industry. This material is in demand for the production of combustion chambers, turbine components operating at high temperatures in high-aggressive media. From this leafy produce engine components — metal gasket cylinder heads, manifolds and exhaust pipes devices. It is used for the sheet metal parts pumps used in acid mine waters. The recommended temperature is long (up to 10 000 hours) the application of the sheet is limited to 750 ° C.
