HN32T alloy intended for manufacturing parts that are stable at high temperatures (up 850ºS) in industrial corrosive environments. Due to the high content of nickel and chromium, parts and fragments of this alloy is characterized by high corrosion resistance and provides high reliability. Depending on the chemical composition of the oscillations vary such as the ductility of the alloy quality, resistivity, and other properties of weldability.

Due to its chemical composition, this steel has high weldability, which enables to produce a wide variety of designs without the use of special technological equipment and to dispense with the final heat treatment. At higher node design requirements or mechanism HN32T alloy is subjected to quenching — heat up to a temperature of 1000 — 1200 ° C followed by cooling in air or water. This normalizes the internal stresses in the alloy, and enhances the strength characteristics of components.
Details, fragments of welded alloy HN32T designed for continuous operation at t ° up to 850 ° C in the oil, oil and gas processing and chemical industries. Made from this alloy pipes of various section, heat exchangers, tanks and the like.
