The A335 specification is a standard established by the ASTM (American Society for Testing and Materials) and is commonly used for alloy steel pipes intended for high-temperature and high-pressure applications.
The A335 specification covers a range of different alloy steel grades, each with its own unique properties and characteristics. Some of the common grades specified in ASTM A335 include:
ASTM A335 P5: This grade contains chromium and molybdenum and is suitable for high-temperature service.
ASTM A335 P9: It has a higher chromium content and is often used in applications involving higher temperatures and pressure.
ASTM A335 P11: Known for its high-temperature strength and resistance to oxidation, this grade is frequently used in power plants and petrochemical facilities.
ASTM A335 P22: This grade has excellent corrosion resistance and is often used in applications involving corrosive environments.
ASTM A335 P91: Known for its high-temperature strength, this grade is used in power generation and other high-temperature applications.
The equivalent of A335 steel depends on the specific grade within the A335 specification. Each grade may have equivalents in other international standards. For example, ASTM A335 P5 may have equivalents in EN 10216-2 (European standard) as 13CrMo4-5, and in DIN 17175 (German standard) as 13CrMo44.
