What Are ASTM A335 P1 Alloy Steel Seamless Pipes?
ASTM A335 P1 Pipes, often referred to as Carbon-Molybdenum or Chrome moly P1 pipe (though its chromium content is minimal or not intentionally added for standard P1), and designated by UNS K11522 Pipe, are seamless ferritic alloy-steel pipes intended for moderate high-temperature service. The "P1" signifies a specific chemical composition within the ASTM A335 standard, characterized primarily by its carbon and molybdenum content (approximately 0.5% Molybdenum). This composition in these Alloy Steel P1 Pipes imparts improved creep resistance and strength at elevated temperatures compared to plain carbon steels.
The seamless manufacturing process ensures uniform strength and structural integrity, making ASTM S335 Grade P1 pipes suitable for applications involving moderate pressures and temperatures where basic carbon steel might prove inadequate over time. The ASME SA335 P1 Pipe is the equivalent standard often specified for boiler and pressure vessel code applications. While P1 is a lower alloy compared to other P-grades like P11 or P22, it serves as an economical solution for specific temperature ranges.
Key Properties & Advantages of ASTM A335 Grade P1 Pipes
Choosing ASTM A335 P1 Pipes from Amardeep Steel offers several key advantages for your moderate high-temperature applications:
- Improved High-Temperature Strength: The molybdenum addition provides better strength and creep resistance at elevated temperatures compared to plain carbon steels.
- Cost-Effectiveness: Offers an economical solution for applications where the extreme properties of higher chrome-moly alloys are not required.
- Good Weldability: Generally considered to have good weldability using common fusion welding techniques, with appropriate preheat and post-weld heat treatment (PWHT) often recommended.
- Versatility: Suitable for a range of moderate-temperature services, including Boiler tube P1 applications in lower-temperature sections.
- Reliability: The seamless construction and alloy composition ensure dependable performance within its designed service conditions.

Heat Treatment of A335 P1 Alloy Steel Pipes
To ensure optimal properties for moderate high-temperature service, ASTM A335 P1 Pipes are supplied in a heat-treated condition:
- Full or Isothermal Anneal: This softens the material, refines its structure, and improves ductility.
- Normalize and Temper: Normalizing refines the grain structure, and subsequent tempering (typically at a minimum of 620°C or 1150°F) enhances toughness and relieves stresses.
The specific heat treatment is detailed on the Mill Test Certificate (MTC).
Applications of ASTM A335 P1 Alloy Steel Seamless Pipes
The reliable performance of ASTM A335 P1 Pipes at moderate elevated temperatures makes them suitable for various applications. Our Alloy Steel P1 Pipes are commonly used in:
- Power Generation: Low-to-moderate temperature steam lines, auxiliary piping, boiler feed water lines, and as Boiler tube P1 in lower temperature sections of industrial and utility boilers.
- Petrochemical Plants: Process piping for fluids and gases at moderate temperatures where the higher alloy content of P5, P9, P11, or P22 is not required.
- Refineries: Utility lines, low-temperature process lines.
- General Industrial Heating: Piping for industrial heating systems and process equipment operating at moderate temperatures.
- Heat Exchangers: Used as Heat exchanger pipe P1 in applications with less aggressive media and moderate temperatures.
While ASTM S335 Grade P1 is a foundational alloy steel, it provides a dependable and economical solution for many moderate P1 high-temperature pipe service requirements.
