Relevance

The circle of KHN32T alloy has high strength and reliability. Along with similar products from chromium-Nickel alloys, it is intended to produce parts which are operated at high temperatures in aggressive chemical environments. Due to the high content of Nickel, chromium, mechanisms and parts made from this alloy have high corrosion resistance, providing increased reliability of the equipment.

Basic properties

Density = to 8.16 g/cm3, coefficient of linear expansion of 13.7 (1/deg K). The mechanical properties of a circle depend on the temperature. In the range t º 20 — 1000 º C Flexural strength will be 60 — 520 N/mm2. The circle has a conductivity in the range of 15.9 to 23.4 W/(m•deg K). This wire, thanks to a good chemical composition has high weldability, which allows the most sophisticated design without special equipment and without additional heat treatment after welding.

The surface of the circle is not susceptible to oxidation during long-term operation and high temperature. A circle of plastic and is resistant to an oxidizing atmosphere, to an atmosphere of ammonia and nitrogen. However, its main drawback is that it does not have stability in the atmosphere of sulfur compounds and sulfur. The circle has a high cost, because of the high cost of the main components — Nickel.

Hardening

Round KHN32T to provide additional rigidity is subjected to quenching at t º 1000 — 1200ºC and then cooled in water or air. It promotes the normalization of internal stresses in the alloy and increasing the strength characteristics of parts.

Use

The basic combination of the components of the alloy, allows the use of round KHN32T in various fields of industry. Having a good combination of chemical resistance and strength, it is widely used in the manufacture of prefabricated parts and welded structures for the equipment for the production of ammonia, in petrochemical plants. Round KHN32T capable of ensuring reliable and continuous operation of structures and components at operating temperatures above 1100 °C under high pressure. The circle KHN32T used in the production of equipment for the metallurgical complex and details of furnaces for heat treatment, power stations.
