Applications of SUS304H stainless steel in high-temperature environments

If you are looking for SUS304H stainless steel for high-temperature environments, GNEE offers a range of high-performance solutions. SUS304H (also known as AISI 304H) is a high-carbon variant of the widely used 304 stainless steel, designed for applications requiring excellent heat resistance and performance in high-temperature environments.

 

What is SUS304H stainless steel?
SUS304H (equivalent to AISI 304H, EN 1.4948) is a high‑carbon austenitic stainless steel specially developed for elevated‑temperature service, containing 18 % Cr, 8–10.5 % Ni​ with a controlled carbon content of 0.04–0.10 %​ to enhance creep resistance and high‑temperature strength. It retains excellent oxidation resistance up to approximately 850 °C, with typical room‑temperature mechanical properties of minimum tensile strength 515 MPa, yield strength ≥ 205 MPa, and elongation ≥ 40 %, ensuring structural stability under prolonged thermal loading.

 

What is the temperature limit of SUS304H stainless steel?

SUS304H is designed to withstand continuous service temperatures up to 800°C (1472°F) and intermittent exposure up to 900°C (1652°F).

 

How does SUS304H differ from SUS304 stainless steel?

SUS304H has a higher carbon content compared to SUS304, which enhances its creep resistance and high-temperature strength, making it more suitable for high-temperature applications.

 

What industries use SUS304H?

SUS304H is commonly used in industries such as power generation, chemical processing, aerospace, and petrochemical, where high-temperature resistance, strength, and corrosion resistance are crucial.

Applications of SUS304H in High-Temperature Environments
