ASTM A335 is a standard specification for seamless ferritic alloy-steel pipe intended for high-temperature service.
This material is commonly used in power plants, refineries, and other industrial settings where high-temperature and high-pressure conditions are encountered. The "A" in ASTM A335 stands for "alloy," indicating that the pipe is made from alloy steel, which typically includes elements such as chromium, molybdenum, and sometimes vanadium to enhance its high-temperature properties.
ASTM A335 pipes are available in various grades, such as P1, P2, P5, P9, P11, P22, P91, and P92, each with specific chemical compositions and mechanical properties to suit different applications. These pipes are designed to withstand high temperatures and pressures while maintaining their strength and integrity over time.
1 This specification 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.
2 Several grades of ferritic steels (see Note 1) are covered. Their compositions are given in Table 1.
Note 1. Ferritic steels in this specification are defined as low- and intermediate-alloy steels containing up to and including 10% chromium.
3 Supplementary requirements (S1 to S7) of an optional nature are provided. These supplementary requirements call for additional tests to be made, and when desired, shall be so stated in the order together with the number of such tests required.
4 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. The inch-pound units shall apply unless the "M" designation of this specification is specified in the order.
Note The dimensionless designator NPS (nominal pipe size) has been substituted in this standard for such traditional terms as "nominal diameter", "size", and "nominal size".
