304H Stainless Steel Properties
UNS S30409 is a high carbon austenitic stainless steel that is typically used in elevated temperature service. Some of the key properties of 304H stainless steel include the following:
- Good formability
- High strength
- Excellent weldability and traceability
- Good oxidation resistance in intermittent service up to 1500°F
- Good stress rupture and creep strength properties
- Higher carbon content for improved high-temperature strength
- Let’s take a more detailed look at some of these key properties.
Formability:
304H austenitic stainless steel can be easily formed using conventional methods. This high-strength material exhibits good ductility in the annealed condition.
High Strength: In the as-welded condition, 304H stainless steel offers higher strengths than standard 304 austenitic stainless steel. This higher strength level is due to the higher carbon content of 304H stainless steel.
Weldability and Brazeability:
Like other austenitic grades, S30409 has excellent weldability and traceability. These properties are due to the presence of austenite in the microstructure of 304H stainless steel.
Oxidation Resistance: The higher carbon content of 304H stainless steel gives this grade improved high-temperature strength compared to standard 304 austenitic stainless steels. As a result, 304H stainless steel is often used in applications where exposure to elevated temperatures is a concern.
Stress Rupture and Creep Strength Properties: The higher carbon content of 304H also gives this grade improved stress to rupture and creep strength properties compared to standard 304 austenitic stainless sheets of steel. These properties make 304H an ideal choice for high-temperature applications such as boiler tubes and piping systems.
304H Stainless steel Uses
304h stainless steel is often used in applications that require superior strength and resistance to corrosion. It is the alloy of choice for chemical processing, petrochemicals, and other industrial processes, as it offers increased strength for such environments. It also has a high resistance to sulfide stress cracking caused by sulfur compounds and good pitting resistance in nearly every chloride environment, making it an excellent choice for piping systems exposed to sea or brackish waters. Its versatility lends it to other uses like refinery heat exchangers, pulp machines, synthetic fiber-producing equipment, pipelines, cladding on steel structures, and food processing equipment, just to name a few.
Conclusion:
SS 304H is a high carbon austenitic stainless steel that offers good formability, high strength, excellent weldability and traceability, and good oxidation resistance in intermittent service up to 1500°F. The higher carbon content of 304H also gives this grade improved stress to rupture and creep strength properties compared to standard304 austenitic stainless steels, making it an ideal choice for high-temperature applications such as boiler tubes and piping systems.
