316H Stainless Steel has a strong resistance to deformación por fluencia when stainless steel pipework is exposed to high temperatures. Ensure reliable performance of your tubería de acero inoxidable y accesorios de acero inoxidable.
What Is 316H Stainless Steel? The High-Temp Workhorse!
316H Stainless Steel (UNS S31609) is a high-carbon version of Acero inoxidable 316. It is an austenitic chromium-nickel-molybdenum alloy. The high carbon content sets it apart, and the higher carbon content improves strength at high temperatures. It also improves creep resistance, which makes 316H stainless steel ideal for applications above 500 degrees Celsius (932 degrees Fahrenheit).
Key Advantages of 316H Stainless Steel
316H stainless steel resists deformation under load. It will not deform even at very high temperatures.
Higher carbono content allows it to resist slow, permanent deformation over time. Good for long-term use.
Like 316 stainless steel, 316H stainless steel resists picaduras. In addition, it resists corrosión en grietas. Contains molybdenum for excellent corrosion resistance.
Its cromo content creates a protective oxide layer. This extends service life in oxidising environments.
316H stainless steel is suitable for chemical processing, power generation and refining. Can handle corrosive media at high temperatures.

316H 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: 316H stainless steel is used for superheater and reheater pipework. Can withstand high heat and steam pressures.
- Refinery Piping: Commonly found in petrochemical plants and can be used to handle hot process fluids. This includes furnaces and crackers.
- Power Plants: Components that come into contact with flue gases or hot steam can be made of 316H Stainless Steel.
- Chemical Process Piping: Used for transporting hot corrosive chemicals. 316H maintains strength and corrosion resistance.
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 316H 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.
While 316H is designed for high temperatures, specific welding procedures are critical. If your application requires it, ensure proper tratamiento posterior a la soldadura.
