ASTM A335 P5 Alloy Steel Pipe Seamless for High Temperature Service
ASTM A335 is a standard for seamless ferritic alloy steel pipes for high temperature applications, and P5 is a material grade under this standard. ASTM A335 P5 nickel alloy pipe is a seamless steel pipe widely used in high-temperature and high-pressure environments, and belongs to the material standard of ASME Boiler and Pressure Vessel Code (BPVC). Mainly used in high-temperature and high-pressure environments such as power plant boilers, petrochemicals, and thermal equipment, such as steam pipelines, superheaters, reheaters, etc.
ASTM A335 P5 alloy steel pipe has a wide range of specifications and sizes, with an outer diameter range of 60.3~765mm and a wall thickness range of 2~120mm. Commonly used specifications and diameters include 60.3, 73, 88.9, and other sizes, and can also be customized according to customers' special needs. The manufacturing process is seamless by hot rolling or cold drawing. The delivery status is usually complete annealing or isothermal annealing, normalizing+tempering, and different delivery statuses can affect the internal structure and properties of the steel pipe. The inspection requirements include chemical composition analysis, mechanical property testing (tensile, hardness), non-destructive testing (ultrasonic, eddy current or hydrostatic testing), and metallographic structure inspection, etc.
The chemical composition design of P5 alloy steel pipe is mainly composed of chromium (Cr) and molybdenum (Mo) as the main alloying elements, with the specific composition as follows (typical values):

ASTM A335 P5 alloy steel pipe can be used for a long time in an environment of ≤ 650 ° C. The chromium content provides antioxidant and sulfide corrosion resistance. Weldable (requiring preheating and post weld heat treatment) and cold bending forming.
