Tronixalloy.com Produces and exports P91 Alloy Steel Pipe. P91 Alloy Steel Pipe is primarily used for high-temperature applications. P91 alloy steel pipes are austenitic compounds, and chilled working improves their elastic and creep properties. These pipes are widely used in industries such as oil & gas, power plants, shipbuilding, and heavy engineering.
The products meet or exceed API, ASTM, ASME, ANSI, and other national and international standards. Cutting fluids based on sulfur-chlorinated water can be successfully used on alloy steel P91 seamless pipes.
Alloy Steel P91 Welded Pipes can be improved by strain aging at relatively low temperatures (700 to 1100 degrees Fahrenheit) if used at temperatures below 1300 degrees Fahrenheit. We offer a wide selection of high-temperature sheet loads of these P91 Alloy Steel pipes, or you can contact us for a custom quote. As austenitic steel, P91 Round Pipes are malleable, easy to frame and weld, and resist stress consumption breaking in chloride-bearing arrangements.
Tronixalloy.Com offers ASTM A335 / ASME SA335 Grade P91 Alloy Steel Seamless Pipes, ANSI B 36.10 Alloy Steel Gr P91 Seamless Round, P91 Pipe, Square, Rectangular, and Hydraulic Pipes. For these alloy steel P91 square pipes, cobalt evaluations of high-speed steel or carbide apparatuses are recommended along with unbending machine arrangements and positive feeds. Alloy Steel P91 Rectangular Pipes that have been cold worked will machine better than strengthened materials.
