Circle, rod KHN32T - ЭП670
Circle brand KHN32T designed to work at t° 700 — 850 °C in an aggressive environment, reducing, oxidizing and nitriding atmospheres, in conditions of carbonization. The oxidation rate in calm air at 800 °C = 0.03 mm/year. High chemical resistance due to the formation on the surface very resistant oxide film. Durability and corrosion resistance give the alloy chromium and Nickel. The latter serves as a solvent, which dissolves other metals. Titanium increases the strength and heat resistance. It also gives ductility and malleability. KHN32T melts at 1400 °C, it is more heat resistant than a limp.
Specific gravity at 20 °C = to 8.16 g/cm3. For comparison, a conventional structural steel is 7.8 g/cm3. Temporary tear resistance (tensile strength) under normal conditions for rod = 480 MPa. At t° of 600 °C decreases to 300 MPa. Round stainless alloy KHN32T has a good performance of the fatigue strength at a temperature above 700 °C. This means that when heated, it tolerates the vibration without rupturing. The alloy has pronounced magnetic properties, does not form scale to t° 1000 °C, cold-resistant. Hardened under pressure treatment. Plastic and ductile, it responds well to hot and cold pressure treatment. It can be welded all types of welding, non-consumable or consumable electrode, plasma welding, submerged arc, protective environment. As such medium is a multicomponent mixture of: Ar2+He2+H2+CO2. Good weldability can make the design without the use of special technological equipment. The finished design does not require additional heat treatment after welding.

Round KHN32T unstable in the atmosphere sulfur compounds, has a high production cost. Nickel and titanium in the composition makes the material more expensive but also more reliable. Therefore, the price of such a range can hardly be regarded as excessive. As the alloy is prone to formation of hardening, it should be before pressure treatment to anneal. For grinding and polishing using abrasive tools of high hardness. The propensity to work hardening should be taken into consideration in machining. Cutting should be carbide tool at low speed and continuously. In order for the tool to cut the previously formed nagaremono area, you need to provide a sufficient depth of cut.

Also in the alloy as impurities are present and other chemicals in small proportions. A good combination of basic elements and the alloy KHN32T widely demanded in various industries. It is driven by a good combination of strength and chemical resistance. It is widely used in the manufacture of welded and prefabricated structures for petrochemical plants, equipment for the production of ammonia. It provides long and trouble-free service life of components and structures under high pressure at operating temperatures up to 850 °C. is also Applied in power plants, in production of metallurgical equipment and components for heat treatment furnaces.
