ASTM A335 P91 Pipe has two different types. There are type 1 and type 2. The type 2 is the most used. The material composition includes carbon, manganese, phosphorus, sulfur, silicon, 8% chromium and molybdenum in the major part. YIZENG is a leading manufacturer of the ASTM A335 P91 Pipe in different dimensions and shapes. There are more alloying elements in smaller quantities such as the vanadium, nitrogen, nickel, aluminum, columbium, titanium and zirconium in the composition. The pipes come under the A335 standard. But the forged or bored pipes can also come under A369.
