ASTM A335 gr P1 Pipe (ASME S/A335, Chorme-Moly) is a seamless ferritic Alloy Steel Pipe for high temperature service. Alloy Steel P1 Pipe and P1 Seamless Pipe are suitable for high temperature application such as bending, flanging (vanstoning), and similar forming operations, and for fusion welding in the power industry and petro-chemical plants. ASTM A335 P11|P12|P22 Alloy Steel Steam Pipe - ANSON Product Scope:ANSON STEEL manufactures full grade and range of ASTM A335 alloy steel pipe, with main grades of P11, P12, P22,P9, pipe of this specification is suitable for high temperature 610ºC, it is used as main steam pipe for power plant, super heater and reheater for heat resistant and good processing performance. ASTM A335 Chrome-Moly Pipe and Featured Grades P11, Featured Grades P9, P11, P22, P91 pipes. This chrome moly pipe featured grades are ASTM A335 P9, P11, P22, P91, so also it could be called as P Grade pipe in some cases. P11 pipe, P22 pipe and P91 pipes are used in power industry and petro-chemical plants, meanwhile, P5 and P9 pipe generally find usage in refineries. ASTM A335 Grade P91 Alloy Steel Seamless Pipe U.S. MetalsCharacteristics of ASTM A335 P91 Type 2 P91 is a chrome moly alloy metal that contains excellent strength and temperature resistance. It is designed for enhanced creep strength, making it a creep strength enhanced ferritic (CSEF). This metal is made by normalizing at 1050 °C, air cooling to 200 °C, and then tempered through heating to 760 °C. Alloy Steel Seamless Pipes - ASTM A335 Gr P1 - Maruti Pipes
