Stainless steel sheet of heat resistant material HN77TYUR Nickel-based multifunctional material with exceptional opportunities. It is available in thickness 0,5−12 mm. There are differences in the accuracy of rolling, the degree of traction, variety of surface treatment, size of cutting, the type of edge. Currently there is no single (world) system of designations of materials rental. Accepted the established alphanumeric code.
1. Letters are designated by the names of main chemical elements (X — chrome, N — Nickel, T — titanium, s — aluminium) R — cerium contained in the alloy HN77TYUR, and its melting (W);
2. The figures reflect the average percentage content of major elements, in this case, as the Nickel-based alloy — 77%.

The quality of the sheet
Stainless steel sheet HN77TYUR relates to an austenitic steel with high corrosion resistance, heat resistance and heat resistance. The presence of the sheet material of chrome provides not only the heat resistance but also chemical and corrosion resistance due to the formation on the surface of the thin protective oxide films. Nickel-based material provides stainless steel sheet with the necessary plasticity and viscosity. This simplifies the process of its processing pressure. It has high strength characteristics in all conditions, good resistance to organic acids, weak mineral acids and nitric acid. However, hydrochloric and sulfuric acid dissolve a leaf. He has a limit short-term strength of 930 MPa and 20% elongation at break. Heat treatment involves quenching from 1080 to 1120 °C with cooling in water.
The sheet density at 20 °C is 8.2 g/cm3. The modulus of elasticity of the first kind of 1.96 MPa and coefficient of thermal (linear) expansion is 16.8 1/deg at 100 °C. Coefficient of thermal conductivity (a 13.9 — 31.1 W/(m•deg) in the temperature range 100 — 900°C). The finished sheet may be subjected to various types of processing, preserving its main properties and aesthetic appearance. Compared with black metal, this sheet provides structural elements of great strength, lightness, durability, and simplifies maintenance. The disadvantages of the leaf relates to its high cost. However, given the possibility of prolonged use without special care, the use of the sheet is more economical in comparison with other materials.

Aerospace, engineering, petrochemical, pharmaceutical industry. This material is popular for the production of combustion chambers of turbine components operating at high temperatures in an environment of increased aggressiveness. It produces sheet metal engine components — metal gaskets cylinder heads, manifolds, and exhaust devices. It is used for sheet metal parts of pumps used in acid mine waters. The recommended temperature for a long (up to 10 000 hours) applications this sheet is limited to 750 °C.
