ХН32Т - Эп670 pipe
The mechanical properties of the pipe vary with temperature. For example, in the range 20 — 1000ºC, the resistance to bending will be 520 — 60 N / sq. Mm. The coefficient of linear expansion is 13.7 (1 / degree K), and the coefficient of thermal conductivity varies in the interval 15.9 — 23.4 W / (m • degree K). Density = 8.16 g / cm³. This steel, due to its good chemical composition, has high weldability, which allows the most complicated structures to be produced without the use of special equipment, and without additional heat treatment at the end of welding operations.
Advantages and disadvantages
The HN32T pipe made of corrosion-resistant special steel is classified as stainless steel. The alloy grade KhN32T, like other chromium-nickel alloys, is intended for the production of parts that are operated at high temperatures (not higher than 1100 ° C) in aggressive chemical media. Due to the high content of nickel, chromium, the mechanisms and parts made of this alloy have high corrosion resistance, providing increased equipment reliability. However, despite the corrosion resistance, these pipes are unstable in the atmosphere of sulfur compounds and sulfur. Due to the high chromium, nickel and titanium content of this alloy, the pipes have a high price, but they are more reliable. Their cost is compensated by the durability and strength of the material.

The pipes of the alloy ХН32Т are used in harsh conditions of aggressive media. Pipes of this type are often used in the form of tanks for the transport of chemically active substances, due to their excellent strength, high corrosion resistance and durability. The HN32T pipe, as a rule, is not always the final product. It is widely used as a blank for punching, cutting, pressing in the manufacture of separators, bearings, etc. rolling elements. The KhN32T pipe is also used in the manufacture of parts of installations in the oil and gas industry that operate at extremely high temperatures, in metallurgy and machine building. The process of production of these pipes requires strict control over compliance with international and domestic requirements for quality and safety, which allows without any restrictions to use them in chemical, food enterprises, in the medical industry.
