What Are ASTM A213 T9 Alloy Steel Seamless Tubes?
ASTM A213 T9 Alloy Steel Seamless Tubes are specialized chromium-molybdenum (often referred to as Chrome-Moly T9 Tube) ferritic alloy steel tubes. Identified by the UNS designation K90941, these tubes are specifically designed for critical high-temperature service. Their composition, primarily featuring 9% chromium and 1% molybdenum, provides excellent resistance to heat, oxidation, and corrosion at elevated temperatures, making them indispensable for applications such as boilers, superheaters, and heat exchangers.
The ASTM A213 specification is the industry standard governing seamless ferritic and austenitic alloy-steel boiler, superheater, and heat-exchanger tubes. Grade T9 within this standard signifies a specific ferritic alloy composition. These tubes are also frequently specified under the equivalent ASME standard, ASME SA 213 T9. The "seamless" nature of these tubes, achieved through processes like hot rolling or cold drawing, ensures a homogenous structure without weld seams, offering superior strength and integrity under high-pressure conditions.

FAQs about ASTM A213 T9 Tubes
What is A213 T9 material?
SA213T9 is a low alloy steel seamless ferritic boiler tube used in super heater elements and heat exchangers. These seamless ferritic tubes are used for their high strength, corrosion resistance and excellent performances in high temperature applications.
What is the composition of SA 213 GR T9?
As for ASTM SA213 T9 Tubing, the typical material composition of SA213 T9 Tubing is max 0.15 Carbon, 0.30-0.60 Manganese, 0.025 Sulfur, 0.025 Phosphorous, 0.90-1.10 Molybdenum, and the physical conditions with the mechanical properties of max tensile strength of 415 Mpa, and a max yield strength of 205 Mpa.
What is ASTM A213 T9, and what is it primarily used for?
ASTM A213 T9 refers to a grade of chromium-molybdenum (specifically 9% Chrome, 1% Moly) ferritic alloy steel seamless tube, designated as UNS S50400. It's primarily used for high-temperature service in applications like boilers, superheaters, and heat exchangers due to its excellent strength and resistance to oxidation and corrosion at elevated temperatures.
What is the difference between T9 and P9 (e.g., ASTM A335 P9)?
Both T9 (from ASTM A213 for tubes) and P9 (from ASTM A335 for pipes) have very similar chemical compositions (9Cr-1Mo) and are designed for high-temperature service. The primary difference lies in the product form and the specific standard's scope and testing requirements. A213 is for seamless boiler, superheater, and heat exchanger tubes, while A335 is for seamless ferritic alloy-steel pipe for high-temperature service.
