Circle HN75MBTYU - EI602
Heat resistance (or resistance to scaling) — this alloy’s ability to resist oxidation at high temperatures, when there is a chemical compound of a metal and oxygen molecules. Increased heat resistance is achieved by adding chromium alloy and other elements that form when heated oxide protective film. At the same time in the oxidation process of change comes to the diffusion of oxygen through the metal oxide film layer. The greater the rate of diffusion of the faster growing thickness on the metal oxide surface. Heat resistance — the ability to withstand high temperatures (above 600 ° C) and does not deform under load. Circle HN75MBTYU — «superalloy» among other alloys. Due to its exceptional qualities, it is used in the most demanding production environments.
The percentage of the circle HN75MBTYU
|to 77.6||19−22||1.8−2.3||up to 1||0.8||0.9−1.3||0.35−0.75||0.35−0.75||0.4||0.12||0.1||to 0.012|
Exceptional performance and reliability of the range is achieved by the fact that the basis of the alloy is nickel: 68,568 — 77.6% chromium and 19 — 22%. Thanks to them, on the surface of the product forms a very thin oxide film which is practically not interact with the external environment. In mechanical or chemical damage this protective layer is instantly restored. Mechanical quality range is stored at high temperatures. The advantages should also include durability and easy processing, easy weldability and minimal care for details.

Production and Application
HN75MBTYU alloy manufactured according to GOST 5632−61. The circle of large diameter (sometimes still called «blanks») also refers to long products. The circle is used in the manufacture of a variety of equipment: high-temperature parts of the combustion chambers with a limited service life, operating at a temperature of about 1000 ° C, and other heat-resistant and heat-resistant products with high resistance to corrosion. Because it makes parts of jet engines and turbines of jet, as this unique alloy retains high strength at high temperatures and under the influence of high pressures and tremendous loads. It is indispensable for the manufacture of parts and components for gas pipeline systems. Plugs, bolts, various threaded connections, studs, nuts of this alloy has high corrosion resistance and high wear resistance.
All HN75MBTYU brands presented products are certified. The technical documentation includes data on the chemical composition, limiting the percentage of impurities; mechanical properties of products. We can buy in bulk, any semi-finished products for large-scale productions. We also offer optimal conditions for retail customers. High level of service and efficiency of service are the face of our company.
