Russian customer purchased 200 tons of A335P92 cold-drawn alloy tubes

A335P92 cold-drawn tube is a ferritic alloy steel, with its main alloying elements including chromium, molybdenum, vanadium, niobium, and nitrogen. The rational proportions of these elements endow the material with excellent high-temperature strength and creep resistance. The cold-drawing process results in a smooth surface, high dimensional accuracy, and a denser internal structure, thus improving overall mechanical properties.

In high-temperature environments, A335P92 material maintains good oxidation and corrosion resistance. Its long-term operating temperature can reach over 600 degrees Celsius, and its short-term operating temperature can be even higher. This makes it one of the main materials chosen for critical components in thermal systems.


A335P92 cold-drawn tubes are primarily used in the manufacture of high-temperature, high-pressure piping systems, such as superheaters, reheaters, and main steam pipes in power plant boilers. In these applications, the pipes need to withstand extremely high temperatures and pressures, thus placing very stringent requirements on the material's performance. A335P92 material not only meets these conditions but also extends the equipment's lifespan and reduces maintenance costs.

This material is also used in cracking units and converter piping in the petrochemical industry. These applications similarly require materials with excellent heat resistance and corrosion resistance. The high-precision dimensions of cold-drawn tubes also facilitate easier installation and reduce the need for subsequent processing.
