ASTM A335 P5 alloy steel pipe

UNS K41545 seamless pipe

15Х5М high-temperature steel pipe

ASTM A335 P5 / UNS K41545 / 15Х5М Seamless Alloy Steel Pipe for High-Temperature Service

ASTM A335 P5 Seamless Alloy Steel Pipe is a seamless ferritic alloy-steel pipe specifically engineered for high-temperature service applications. This product conforms to the Standard Specification for Seamless Ferritic Alloy-Steel Pipe for High-Temperature Service (ASTM A335/A335M) and is designed for bending, flanging, forming operations, and fusion welding.

Standard Specifications

Standard: ASTM A335/A335M
Grade: P5
UNS Designation: K41545
Russian Analog: ГОСТ 550-2020 15Х5М
Manufacturing Process: Seamless

Material Characteristics

ASTM A335 P5 pipe is a chromium-molybdenum (Cr-Mo) alloy steel that provides excellent high-temperature strength, oxidation resistance, and improved corrosion resistance compared to carbon steels. As a ferritic steel, it offers superior structural stability under prolonged high-heat exposure and exceptional creep strength for resisting deformation under stress at elevated temperatures.
