Product Description

ASTM A213 T9 Alloy Steel Seamless Furnace and Heat Exchanger Tubes

ASME SA213/ASTM A213 This specification covers seamless ferritic and austenitic steel boiler, superheater, and heat-exchanger tubes, designated Grades T5, TP304, TP321, etc. ASTM A213 T9 (SA213 T9) is a chromium-molybdenum (Cr-Mo) alloy steel specifically designed for high-temperature and high-pressure environments. Its unique composition (9% Cr, 1% Mo) provides excellent oxidation resistance, creep strength, and corrosion resistance.

Chemical Composition (%) max
  • Carbon: 0.15
  • Manganese: 0.30-0.60
  • Phosphorus: 0.025
  • Sulfur: 0.025
  • Silicon: 0.25-1.00
  • Chromium: 8.0-10.0
  • Molybdenum: 0.90-1.10
Mechanical Properties
  • Subcritical Annealing /Tempering Temperature, min or range: 1250 °F [675°C]
  • Tensile Strength, min.: 60ksi [415MPa]
  • Yield Strength, min.: 30ksi [205MPa]
  • Elongation in 2 in. or 50mm, min.: 30%
  • Brinell/Vickers: 179HBW/190HV
  • Rockwell: 89HRB
Advantages
  • Better Oxidation Resistance than T11/T22 at higher temps
  • Higher Creep Strength compared to carbon steel
  • Good Weldability (though pre/post-weld heat treatment is needed)
  • Cost-Effective compared to stainless steels (e.g., 304H, 321H) for certain temp ranges
Applications

Power Generation (Boilers & Superheaters)

  • Superheater & Reheater Tubes: T9 tubes withstand steam temperatures up to 650°C (1200°F) without excessive scaling
  • Boiler Tubes: Used in high-pressure boilers where carbon steel would fail due to oxidation
  • Heat Recovery Steam Generators (HRSGs): Resists thermal fatigue in combined-cycle power plants

Petrochemical & Refinery Applications

  • Furnace Tubes & Heat Exchangers: Handles sulfur-rich environments better than low-alloy steels
  • Catalyst Tubes in Refineries: Resists carburization and hydrogen attack at high temps

Chemical Processing Plants

  • High-Temperature Process Piping: Used where corrosive gases or steam are present
  • Thermal Cracking Units: Maintains strength under cyclic heating conditions
