ASTM A335 / A335M - 21 Standard Specification for Scope. 1.1 This specification 2 covers nominal wall and minimum wall seamless ferritic alloy-steel pipe intended for high-temperature service. Pipe ordered to this specification shall be suitable for bending, flanging (vanstoning), and similar forming operations, and for fusion welding. Selection will depend upon design, service conditions, mechanical properties, and high-temperature characteristics.
ASTM A335 is the seamless ferritic alloy steel pipe that used in high-temperature services and boiler industry. Common used Grade P5, P9, P11, P22, P91. ASTM A335 pipe also named as ASME S/A335 Chrome-Moly pipe, it is a type of seamless pipe used in high temperature environments of 540 750 °C.
ASTM A335 P9 Alloy Steel Seamless Pipe and SA 335 P9 ASTM A335 P9 Seamless Pipe is one of the chromium molybdenum alloy pipes. This kind of material is used for high temperature and pressure applications. The thermal expansion rate of this material is considerably less so that it does not lose its form or shape under high temperatures.
