Alloy Steel UNS K41545 Seamless Tubes, Chrome Moly SA213 T5 Seamless Boiler Tubing


A213 T5 alloy steel tube refers to a tube made from a specific grade of alloy steel, known as T5, under the ASTM A213 standard. Here’s a breakdown of what it entails:

ASTM A213 Standard

  • ASTM A213 is a standard specification by ASTM International for seamless ferritic and austenitic alloy-steel boiler, superheater, and heat-exchanger tubes. It specifies the material requirements, including the composition, mechanical properties, and testing criteria for various grades of alloy steel.

T5 Alloy Steel

  • T5 is a type of alloy steel, often referred to as 5% chromium steel. The general composition of T5 steel is:
    • Chromium (Cr): 4.5-5.5%
    • Molybdenum (Mo): 0.44-0.65%
    • Carbon (C): 0.45% maximum
    • Other elements may include silicon, manganese, and traces of sulfur and phosphorus.
    T5 steel is known for its high-temperature strength and oxidation resistance, making it suitable for use in heat exchangers, superheaters, and steam boilers, especially in industries like power generation, chemical processing, and petrochemical applications.

Properties of A213 T5 Alloy Steel Tube:

  • High-Temperature Resistance: T5 tubes can withstand high temperatures, typically around 900°F (480°C), and are resistant to oxidation and scaling at elevated temperatures.
  • Mechanical Properties: It has good tensile strength and resistance to stress corrosion cracking, particularly in high-pressure environments.
  • Applications: Commonly used in steam and gas turbines, power plants, and other high-temperature systems.

Manufacturing Process:

  • The A213 T5 alloy steel tube is generally produced via a seamless manufacturing process, meaning it’s made from a solid billet that’s heated and extruded into a tube shape without seams or welds.
