Products Description
A335 P5 alloy pipe is a high-temperature alloy steel pipe widely used in high-temperature and high-pressure environments in industries such as chemical, petroleum, natural gas, and power. Its main material composition is iron (Fe), containing approximately 5% chromium (Cr) and other elements such as molybdenum (Mo) and carbon (C), which provide good high-temperature resistance, corrosion resistance, and oxidation resistance.
According to the ASTM A335 standard, the applicable specifications of A335 P5 alloy pipe mainly include outer diameter, wall thickness, and length. The outer diameter range is typically from 1/2 inch to 24 inches (approximately 12.7mm to 609.6mm), with wall thickness ranging from Schedule 10 to Schedule 160. Common wall thickness ranges from 0.5mm to 30mm.
In the manufacturing process, A335 P5 alloy pipe is typically produced using seamless or welded methods, offering good mechanical properties and weldability. It exhibits excellent performance in tensile strength (TS) and yield strength (YS) under high-temperature conditions, generally maintaining good strength and toughness above 500.
Additionally, A335 P5 alloy pipe undergoes heat treatment, such as normalizing or tempering, to enhance its structural stability and crack resistance. These pipes usually require strict non-destructive testing, chemical composition analysis, and mechanical property testing to ensure compliance with relevant standards and customer requirements.

FAQ
What is ASTM A335 P5 material?
A335/SA335 P5 is a seamless ferritic alloy-steel pipe used for high-temperature applications. These pipes are versatile and can be used to transmit water, oil and natural gas. Key to the composition of chrome moly alloy P5 is the addition of chromium and molybdenum.
What are the grades of ASTM A335?
ASTM A335 pipe, also known as Chrome-Moly Alloy Pipe, is widely used in various industries for high temperature and high pressure services. It is available in different grades such as P5, P9, P11, P22, and P91.
What is the difference between P5 and P9 material?
P5 contains 0.5-9% chromium and 0.5-9% molybdenum, while P9 contains 9% chromium and 1-1.5% molybdenum, P11 contains 11% chromium and 1.25-1.5% molybdenum and P12 contains 12% chromium and 1.25-1.5% molybdenum.
What is the difference between P5 and P10?
P5 offers superior clarity but at a higher cost, while P10 provides a cost-effective solution with acceptable clarity for many outdoor and long-distance viewing applications.
