Material Overview: TP304 Stainless Steel

TP304 is a versatile austenitic stainless steel grade, also known by its equivalent designation 1.4301 under EN standards. It is characterized by its 18% chromium (Cr) and 8% nickel (Ni) composition, which provides excellent corrosion resistance, high-temperature performance, and weldability.

Key Benefits of TP304 Stainless Steel

• Corrosion Resistance: Excellent resistance to oxidation and corrosion in both oxidizing and moderately reducing environments.
• High-Temperature Strength: Withstands temperatures up to 870°C, making it ideal for fired heater applications.
• Good Weldability: Easily welded without post-weld annealing in most applications.
• Versatility: Suitable for both plain (bare) tubes and finned tube applications in heat exchanger and fired heater systems.

Chemical Composition and Mechanical Properties

Applications in Fired Heater (API 560)

TP304 stainless steel seamless pipes serve as a crucial component in fired heaters, which are widely used in petrochemical, refinery, and power generation industries. These heaters rely on high-quality tubes to efficiently transfer heat under extreme temperature and pressure conditions.

Bare Tubes (Plain Tubes)

• Used in convection sections and radiant coils due to their excellent thermal conductivity and corrosion resistance.

Finned Tubes

• TP304 is a preferred base tube material for manufacturing finned tubes, enhancing heat transfer efficiency in fired heaters.
• Excellent mechanical properties ensure durability and performance over extended operational periods.

API 560-compliant fired heaters benefit from TP304’s high strength and resistance to oxidation, making it a reliable choice for critical applications.
