Stainless steel 304H fasteners are made of austenitic stainless steel with 18-20% chromium and 8-10% nickel, with higher carbon content than 304L. This material strengthens and can withstand heat transfer, so the top edge is larger. They exhibit excellent mechanical properties such as high tensile strength and oxidation resistance. Benefits include excellent performance in tropical environments, excellent corrosion resistance and durability. These fasteners are ideal for use in the pharmaceutical, power generation and petrochemical industries, ensuring reliable performance under extreme conditions.

A high-carbon version of 304 stainless steel, stainless steel 304H has a higher carbon content (0.04–0.10%) for improved strength at high temperatures. 18–20% chromium, 8–11% nickel, and trace amounts of manganese, silicon, and phosphorus make up its composition. 304H has a yield strength of 240 MPa, a tensile strength of roughly 585 MPa, and good toughness and ductility. It is appropriate for pressure-containing and structural components in high-temperature service because it can tolerate high temperatures and maintains exceptional corrosion resistance, especially in oxidising environments.
Stainless steel 304H fasteners are widely used in applications that need to be strong at high temperatures and resistant to corrosion. They are perfect for power plant and refinery piping systems, boilers, heat exchangers, and pressure vessels. These fasteners are widely used in the petrochemical, chemical processing, and oil and gas sectors and exhibit dependable performance in high-pressure steam environments. They are also appropriate for boiler and heat treatment equipment due to their resistance to oxidation and scaling at high temperatures. 304H fasteners are a popular option for mechanical and structural applications under harsh service conditions because of their durability and weldability.
