Product Description

ASTM A213 T9 alloy steel tube is a seamless steel tube made of ferritic and austenitic alloy steel, compliant with ASTM A213/A213M specification for seamless steel tubes used in boilers, superheaters, and heat exchangers. The product also meets TSG D7002 pressure pipeline components type test requirements.

ASTM A213 T9 is a ferritic alloy steel with a matrix microstructure primarily composed of ferrite (tempered martensite). With nearly double the chromium content of T5, it offers significantly improved high temperature strength and oxidation resistance. These tubes feature high strength, toughness, and corrosion resistance with tensile strength ≥ 415MPa, yield point ≥ 205MPa, elongation ≥ 30%, and hardness HBW ≤ 179, making them ideal for harsh high-temperature, high-pressure environments.

Manufacturing Process

Steelmaking: Precise chemical composition control ensures tube performance and stability
Rolling: Maintains dimensional accuracy and wall thickness uniformity while preventing surface defects
Heat treatment: Stabilizes tubes, eliminates internal stress, and enhances toughness and corrosion resistance

Applications

ASTM A213 T9 alloy steel tubes are ideal for high-temperature, high-pressure environments across multiple industries:

Power plant boilers: Superheaters, reheaters, and steam piping systems requiring excellent heat resistance
Petrochemical industry: High-temperature reactors, heat exchangers, and piping systems for corrosive media
Nuclear energy: Cooling systems and components requiring radiation resistance
Shipbuilding: Boiler systems and steam turbines needing vibration resistance
Industrial equipment: Metallurgical, glass manufacturing, and papermaking equipment for harsh environments
