304H stainless steel provides a solution when pipework is often exposed to high temperatures. Designed for demanding high-temperature service, it avoids costly deformación por fluencia. Ensure reliable performance of your tubería de acero inoxidable y accesorios de acero inoxidable.
What Is 304H Stainless Steel?
Stainless steel 304H (UNS S30409) is a high-carbon version of stainless steel 304. It is an aleación austenítica de cromo y níquel. The high carbon content increases strength at high temperatures and enhances creep resistance. This makes 304H stainless steel ideal for applications above 500 degrees Celsius (932 degrees Fahrenheit).
Key Advantages of 304H Stainless Steel
Stainless Steel 304H retains its strength at very high temperatures and resists deformation under load.
Higher carbono content increases creep strength. It resists slow, permanent deformation over time.
los cromo content creates a protective oxide layer that prevents surface degradation. This ensures longevity in oxidising environments.
Despite its high carbon content, Stainless Steel 304H is easy to weld.
The 304H Steel is used in many industries. It is used in chemical processing, power generation and refining, and can handle corrosive media at high temperatures.

304H Stainless Steel in High-Temperature Piping Applications
- Pressure Vessels: Handling of high temperature and high pressure vessels including steam headers and intercambiadores de calor.
- Boiler components: The 304H steel is used for superheater and reheater pipework. They can withstand high heat and steam pressures.
- Refinery Piping: Commonly found in petrochemical plants, it handles hot process fluids. This includes furnaces and crackers.
- Power Plants: Components exposed to flue gases or hot steam can be made of 304H Stainless Steel.
- Industrial Furnaces: Used in radiant tubes, mufflers and heat treatment units. Because it prevents scaling and oxidation at very high temperatures.
Sourcing 316H Stainless Steel Pipe and Fittings
Comprobar el cumplimiento de Normas ASTM. La norma ASTM A312 cubre sin costuras y tubo de acero inoxidable soldado. La norma ASTM A403 cubre la forja acero inoxidable austenítico accesorios.
Asegúrese de que las tuberías y accesorios cumplen las dimensiones requeridas. Esto incluye las especificaciones (por ejemplo, Sch 10S, Sch 40S). El ajuste correcto es fundamental.
Ver documento de especificaciones de tubos de acero inoxidable
Trabajar con fabricantes reputados who offer reliable 304H steel products and have certificaciones(por ejemplo ISO 9001 y CE-PED).
Pida siempre Informes de ensayos de materialesque confirman la composición química y verifican las propiedades mecánicas.
304H is designed for high temperatures, but specific procedimientos de soldadura are also important. Please ensure proper tratamiento posterior a la soldadura.
