Circle marks HN32T designed to operate at t ° 700 — 850 ° C in corrosive environments reducing, oxidizing and nitriding atmosphere in the carburizing conditions. The oxidation rate in still air at 800 ° C = 0,03 mm / year. High chemical resistance due to the formation on the surface of a very resistant oxide film. Strength and corrosion resistance and impart nickel chromium alloy. The latter serves as a solvent in which the other metals are dissolved. Titan — increases the strength and heat resistance. He gives ductility and malleability. HN32T melts at 1400 ° C, it is more zharoprochen than limping.
Specific gravity at 20 ° C = 8,16 g / cm³. For comparison — in the ordinary structural steel — 7.8 g / cm³. Tensile strength (tensile strength) under normal conditions for bar = 480 MPa. At t ° to 600 ° C drops to 300 MPa. Circle of stainless steel alloy HN32T has good performance fatigue strength at t ° above 700 ° C. This means that when heated, it is resistant to vibration, without being destroyed. The alloy has no distinct magnetic properties, does not form scale t ° to 1000 ° C, cold-resistant. The reinforcement by pressure treatment. Plastic and viscous, it lends itself well to hot and cold pressure treatment. It can be welded by all known types of welding: non-consumable or consumable electrode, plasma welding, submerged in a protective environment. As such a medium is a multi-component mixture: Ar2 + He2 + H2 + CO2. Good weldability allows to produce designs without the use of special technological equipment. Prepared structure does not require additional heat treatment after the welding.

Circle HN32T unstable in the atmosphere of sulfur compounds, has a high production cost. Nickel and titanium in the composition makes the material more expensive, but at the same time and more reliable. Therefore, this price range are unlikely to be regarded as excessive. As the alloy is prone to the formation of hardening, it must be annealed prior to pressure treatment. For grinding and polishing use abrasive tools increased hardness. The tendency to work hardening should be taken into account when machining. Carbide cutting tool should be at a low speed and continuously. To make the tool cut the previously formed work-hardened zone, it is necessary to provide sufficient depth of cut.

Also in the alloy as impurities are present, and other elements in minor proportions. It is a successful combination of basic elements and makes a range of alloy HN32T widely demanded in various industries. Its application is determined by a good combination of strength and chemical resistance. It is widely used in the manufacture of parts and welded structures for petrochemical plants, equipment for the production of ammonia. It provides a long and trouble-free operation at high pressure components and structures at operating temperatures up to 850 ° C. It is also used in power plants, in the production of metallurgical equipment and parts for heat treatment furnaces.
