ASTM A335, also known as ASME SA335, is a standard specification for seamless ferritic alloy steel pipe for high-temperature service. The most common alloy steel used in this specification is the P grade, specifically P9.

P9 alloy steel tubes, as specified under ASTM A335 and ASME SA335, are primarily utilized in power generation systems, particularly in steam boiler tubing and superheater tubes where high temperature resistance and strength are required. The 'P9' denotes that the steel is a ferritic alloy with specific chemical compositions that include:

The production of P9 alloy steel seamless tubes typically follows strict quality control measures to ensure compliance with ASTM A335/ASME SA335 standards. This includes rigorous testing for mechanical properties, chemical composition, and dimensional accuracy to guarantee the tubes meet the required specifications for their intended use.
