Alloy Steel ASTM A335 P5, P9, P11, P22, P91 pipes, known as Chrome-Moly Alloy Pipes, are highly sought-after in various industries for their exceptional performance in high-temperature and high-pressure environments. As Manufacturers, Suppliers, Stockists, and Exporters, Metinox Overseas offers a wide range of ASTM A335 pipes to meet diverse industrial requirements.
What sets ASTM A335 pipes apart is their seamless design, specifically engineered to withstand temperatures ranging from 540 to 750 °C. These pipes are commonly referred to as chrome moly pipes due to their high Chromium and Molybdenum content. The presence of Molybdenum significantly enhances the strength, elasticity, hardenability, and overall quality of the pipes, making them ideal for demanding applications.
