A335 P91 specification are many and these include Grade 91 and P-91. A335 P91 Equivalent Standards are GOST 550-75, ASTM A213, E9015-B9, ASME SA213, EN 10216-2 and NBR 5603.  The formation of A335 P91 takes place by normalizing it at 1050 °C and this is then air cooled down to 200 °C. After that, this is then tempered by heating it to 760 °C. The cooling rates and the temperatures are extremely important when it comes to A335 P91 material. The heat treatment for A335 P91 pipes can be N+T / Q+T, A / N+T and N+T.

ASTM A335 P91 material properties are that it is a mixture of 1 % Molybdenum and 9 % Chromium. Because of the presence of Molybdenum, the creep resistance of the material is increased. As a result of Chromium being present in the material, its oxidation resistance is increased and it also gets high temperature strength. Also present in A335 P91 are smaller quantities of Manganese and Nickel and because of these being present, the hardenability of the material increases. The Chemical Composition of A335 P91 is Silicon (max.) 0.50, Manganese 0.30 - 0.60, Carbon (max.) 0.08 - 0.12, Chromium 4.00- 6.00, Phosphorus (max.) 0.025 and Molybdenum 0.45-0.65.

The weight of an A335 P91 would vary and this would depend on the pipe’s physical volume and the weight density of the material of which the pipe is made of. ASTM A335 P91 pipe weight can be very easily found out by using the pipe weight calculator and the best part is that this calculator is available for use for free, at our site. All that has to be done is enter the blank fields in the calculator, with the required quantities, and one gets the weight of the A335 P91 pipe.
