ASTM A213 TP321 / S32100 / 12Х18Н10Т Seamless Tube
High-temperature and corrosion-resistant seamless austenitic stainless steel tubing engineered for demanding industrial applications.
Product Overview
ASTM A213 TP321 is a seamless austenitic stainless steel tube specifically engineered for high-temperature and corrosive service environments. The grade is stabilized with titanium, which provides exceptional resistance to intergranular corrosion and makes it suitable for a wide range of demanding industrial applications, from boilers to chemical processing equipment.
Standards and Specifications
This product is manufactured in strict compliance with the latest international standards:
  • Primary Standard: ASTM A213/A213M - Standard Specification for Seamless Ferritic and Austenitic Alloy-Steel Boiler, Superheater, and Heat-Exchanger Tubes
  • Related Standard: ASTM A312/A312M for seamless austenitic stainless steel pipes
  • Key Designation: The "TP" stands for "Tube, Pipe." The "H" variant (TP321H) has a higher carbon content for improved creep-rupture strength at elevated temperatures
  • Common Size Range: While custom sizes are available, typical tubing supplied to this specification has an outside diameter ranging from 3.2 mm (1/8 in) to 127 mm (5 in) with wall thicknesses from 0.4 mm to 12.7 mm
Material and Chemical Composition
TP321 is a titanium-stabilized derivative of the classic 18-8 (Cr-Ni) stainless steel. The addition of titanium (at least 5 times the carbon content) prevents chromium carbide precipitation at grain boundaries during high-temperature exposure, thereby maintaining its corrosion resistance.
The Russian grade 12Х18Н10Т is a direct equivalent, sharing nearly identical chemical and mechanical properties, making this tubing a versatile choice for global projects.
A typical chemical composition is shown in the table below:
Carbon (C) Manganese (Mn) Phosphorus (P) Sulfur (S) Silicon (Si) Chromium (Cr) Nickel (Ni) Titanium (Ti)
0.08% 2.00% 0.045% 0.030% 1.00% 17.0 - 19.0% 9.0 - 12.0% 5C - 0.70%
Mechanical and Physical Properties
ASTM A213 TP321 tubes are required to undergo mechanical testing, including tension and flattening tests, and are supplied in a heat-treated condition. The following table outlines its key mechanical properties at room temperature.
Property Typical Value Standard / Condition
Tensile Strength ≥ 515 MPa (75 ksi) ASTM A213
Yield Strength (0.2% Offset) ≥ 205 MPa (30 ksi) ASTM A213
Elongation ≥ 35% In 2 inches or 50 mm
Hardness ≤ 192 HB / 90 HRB Brinell or Rockwell B
Primary Advantage Excellent high-temperature strength & intergranular corrosion resistance Stabilized with Titanium
Primary Applications
Due to its stability and strength under heat, TP321 seamless tubes are critical components in several heavy industries:
  • Heat Exchangers & Boilers: Widely used in boiler superheater and reheater tubes, heat exchangers, and condenser tubes
  • Petrochemical Industry: Ideal for refinery piping, furnace components, and equipment handling corrosive chemicals
  • Power Generation: Suitable for high-temperature steam and feedwater lines in fossil fuel power plants
  • Automotive & Aerospace: Used in engine exhaust systems and other high-temperature assemblies
