Global Supplier of High Quality Alloy Steel P9 Seamless Pipe, Alloy Steel Pipe P9, A335 P9 Alloy Steel Seamless Pipe, ASTM A335 P9 High Pressure Steel Pipe, ASTM A691 Alloy Steel EFW Pipe, ASME SA335 Grade P9 Alloy Steel Pipe Supplier in Mumbai, India.

A335 P9 material composition consists of Silicon(max.) 0.50, Molybdenum (0.45 - 0.65), Carbon(max.) 0.15, Chromium (4.00 - 6.00), and Manganese (0.30 - 60). It has a UNS designation of S50400. The minimum yield strength of A335 P9 pipes is 205 MPa, the minimum tensile strength is 415 MPa, and the minimum elongation % is 30/20 L/T. Surface treatment options for A335 P9 include phosphating, varnishing, shot blasting, oil-dipping, and passivation. Flattening tests, surface and dimension tests, mechanical properties tests, hardness tests, chemical composition inspections, and bending tests are all used to test and inspect A335 P9 pipes, among other methods.

The applications for alloy steel ASTM A335 P9 pipe are many. They are found all over the globe in various sectors, including electric power, petroleum, boilers, chemicals, oil and gas, and many other fields. One of the reasons why A335 P9 pipe is in such high demand in various applications is that it has good corrosion resistance and is very resistant to extreme temperatures, both high and low in temperature. When it comes to flanging or bending and several other related applications like fusion welding, the A335 P9 pipe is unsurpassed in its performance. It is important to note that the A335 P9 pipe has been designed for high-temperature applications.

A335 P9 pipe is made of steel. Thermal conductivity will vary from a range of 15.1 at 1500 degrees Fahrenheit to 21 at 800 degrees Fahrenheit to 23.5 at 70 degrees Fahrenheit. For example, the thermal conductivity may be 6.4 at 70 degrees Fahrenheit, 6.5 at 100 degrees Fahrenheit, 7.3 at 500 degrees Fahrenheit, and even at 7.3 degrees Fahrenheit, the thermal conductivity could still be 550 degrees Fahrenheit. Depending on the value of 7, it might be as low as 600, as high as 850, or even higher than 900. At 8.1, it may be as high as 1000 or even as high as 1050. AISI 335 P9 Alloy Steel Pipe is a kind of Chrome-Moly Pipe that is the industry standard for seamless ferritic Alloy-Steel Pipe made in nominal or minimum wall thickness for use in high-temperature applications.
