ASTM A213 TP321H bright seamless tube is a special type of pipe designed to solve the dual challenges of "high-temperature strength" and "corrosion resistance."
Its most precise application is in critical heat exchange equipment in petrochemical, power plant boiler, and other fields requiring high temperature, high pressure, and strict resistance to intergranular corrosion, especially in operating conditions above 540°C where the equipment may face "wet-dry alternation" or corrosive condensate generation.
 
The following are its core application scenarios and reasons for choosing it:
 
The "H" in TP321H represents the high-temperature grade. Unlike ordinary 321 stainless steel with a carbon content ≤0.08%, 321H has a carbon content controlled within a higher range of 0.04-0.10%, ensuring higher creep rupture strength and endurance strength at high temperatures. Simultaneously, the addition of titanium as a stabilizing element enables it to resist intergranular corrosion.
Bright annealing treatment results in a smooth, oxide-free inner and outer surface with a high degree of surface finish. For heat exchange tubes, the inner wall is smoother, the resistance to medium flow is smaller, and it is less prone to scaling.

 

ASTM A213 For Grade TP321H.Chemical Composition
Element Composition (% by weight)
Carbon (C) 0.04 – 0.10
Manganese (Mn) 2.00 max
Phosphorus (P) 0.045 max
Sulfur (S) 0.030 max
Silicon (Si) 1.00 max
Nickel (Ni) 9.0 – 13.0
Chromium (Cr) 17.0 – 20.0
Titanium (Ti) 5 x (C + N) min to 0.70 max
Note: Titanium content shall not be less than five times the carbon plus nitrogen content and not more than 0.70%. Nitrogen content is typically ≤ 0.10% unless otherwise specified.

 

ASTM A213 For Grade TP321H. Mechanical Properties
Property Value
Tensile Strength (min.) 515 MPa (75 ksi)
Yield Strength (0.2% offset, min.) 205 MPa (30 ksi)
Elongation (in 2 inches or 50 mm, min.) 35%
Hardness (max.) 90 HRB (Rockwell B)

 

Applications:
