ASME SA213 TP304H Bright Annealed Stainless Steel Seamless Tube

ASME SA213 TP304H is a high-temperature grade stainless steel belonging to the Austenitic Stainless Steel Family. It is designed for high-temperature applications, specifically in industries like power plants, petrochemicals, chemical processing, and boilers. Bright annealed stainless steel seamless tubing offers enhanced surface finish and improved corrosion resistance, making it an excellent choice for critical industrial applications.

Material Composition (Chemical Properties of TP304H)

This grade is a chromium-nickel-based alloy with the following chemical composition, according to the ASME standard:

Element	Composition (%)
Carbon (C)	0.04–0.10
Manganese (Mn)	≤ 2.00
Phosphorus (P)	≤ 0.045
Sulfur (S)	≤ 0.030
Silicon (Si)	≤ 1.00
Chromium (Cr)	18.0–20.0
Nickel (Ni)	8.0–11.0
Nitrogen (N)	≤ 0.10
Iron (Fe)	Balance

The high carbon content (C: 0.04-0.10%) in TP304H contributes to improved strength under high temperatures.
Chromium and nickel provide excellent corrosion and oxidation resistance.

Features and Applications

Bright Annealed Finish
- Bright annealing is a specialized heat treatment process performed in a controlled atmosphere to create a luminous, reflective surface finish.
- It enhances the corrosion resistance of the tube and minimizes oxidation.
Seamless Tubing
- Seamless manufacturing ensures uniformity, avoiding weak spots like welded seams, for superior mechanical properties and pressure resistance.
- It meets stringent cleanliness and tolerance standards critical for high-temperature and corrosive environments.
High-Temperature Strength
- TP304H is specifically designed for elevated temperature applications due to its excellent creep resistance and strength retention at high temperatures.
- Commonly used in environments up to 650°C (1202°F).
Corrosion Resistance
- Suitable for use in mildly corrosive environments, such as oxidizing acids and chloride-containing applications.
- Resistant to general corrosion, pitting, and stress corrosion cracking.
Applications
TP304H finds extensive use in the following sectors:
- Power Plants: Boiler and heat exchanger tubes.
- Petrochemical Industry: Refinery units, catalytic systems.
- Chemical Processing: Pipe transport for acidic chemicals under extreme heat.
- Oil & Gas: High-pressure, high-temperature piping systems.
- Food & Pharmaceutical Industry: Due to its sanitary surface and corrosion properties.

Mechanical Properties

Property	TP304H Specification
Tensile Strength (MPa)	Minimum 515
Yield Strength (MPa)	Minimum 205
Elongation (%)	Minimum 35
Hardness (HBW/HRB)	Max 192 (HBW) / Max 90 (HRB)

Advantages of Bright Annealed Tubing

Enhanced Corrosion Resistance: The smooth and reflective finish reduces the risk of surface contaminants.
Improved Aesthetic Appeal: The reflective surface is clean and uniform, suitable for visible installations.
Ease of Cleaning: Particularly useful in sanitary and pharmaceutical applications.
Longer Service Life: Bright annealing significantly reduces contamination risks and enhances the tube’s resistance to oxidation and pitting.
