Here's an introduction to Stainless Steel 304H flanges:

The considerably high content of Chromium and Nickel helps our ASTM A182 SS 304H Blind Flanges to function effortlessly in the nitric acid and acetic acid surroundings. Hence, the petroleum refining and chemical processing industry relies on these flanges.

Savoy Piping inc is one of the professional manufacturers and suppliers of flanges SS 304H, which is a steel alloy with a minimum of 10.5% chromium by mass. Our 304H stainless steel slide flanges are outstanding for their corrosion resistance and are widely used for food handling and cutlery among many other applications. This 304H stainless steel threaded flange is not susceptible to corrosion, rust or water stains like ordinary steels. However, our 304H stainless steel weld neck flange is not completely resistant to stains in low oxygen, high salinity or low airflow environments. These 304H stainless steel blind flanges are used where steel properties and corrosion resistance are required.

Our UNS S30409 Stainless Steel Socket Weld Flange differs from carbon steel in the amount of chromium present. These unprotected 304H stainless steel flanges are susceptible to rust when exposed to air and moisture. Since iron oxide has a lower density than these 304H stainless steel washer type flanges, this film expands and has a tendency to peel and fall off. For comparison, our 304H stainless steel eyeglass blind flange and Butt Weld Fittings contains enough chromium to undergo passivation, forming an inert chromium oxide film on the surface. This grade prevents further corrosion by preventing oxygen diffusion to the surface of these 304H stainless steel gasket flanges and prevents corrosion from spreading through most metals.

Stainless Steel 304H Flanges are crucial components in piping systems that facilitate the connection of pipes, valves, and other equipment. The "304H" designation refers to the specific grade of stainless steel, with "H" indicating a higher carbon content compared to standard 304 stainless steel. This higher carbon content enhances the material's high-temperature strength and makes it suitable for applications involving elevated temperatures.

Material Composition:

  • Stainless Steel 304H is an austenitic stainless steel alloy with a higher carbon content (0.04-0.10%) compared to the standard 304 grade. This composition provides improved high-temperature strength and creep resistance.

Corrosion Resistance:

  • Like other stainless steel alloys, 304H exhibits excellent corrosion resistance, making it suitable for applications in various industries, including chemical, petrochemical, food processing, and more.

High-Temperature Applications:

  • The elevated carbon content in 304H enhances its performance at higher temperatures, making it suitable for applications such as heat exchangers, boiler components, and other high-temperature environments.

Flange Types:

  • Stainless Steel 304H flanges come in various types, including slip-on flanges, weld neck flanges, socket weld flanges, blind flanges, and lap joint flanges, among others. Each type serves a specific purpose in piping systems, offering flexibility in design and installation.

Standards and Specifications:

  • Stainless Steel 304H flanges adhere to industry standards and specifications, ensuring compatibility and interchangeability. Common standards include ASTM A182 and ASME B16.5, which provide guidelines for manufacturing and dimensions.


  • 304H flanges find applications in industries where elevated temperatures and corrosive environments are common, such as chemical processing, oil and gas, power generation, and refining. Their resistance to oxidation and corrosion makes them suitable for various challenging conditions.

Fabrication and Welding:

  • Stainless Steel 304H is readily weldable using common welding techniques. Proper welding procedures are essential to maintain the corrosion resistance and mechanical properties of the material.

Maintenance and Durability:

  • Stainless Steel 304H flanges require minimal maintenance and offer long-term durability, making them a cost-effective choice for critical applications.

In summary, Stainless Steel 304H Flanges are reliable and versatile components used in piping systems, particularly in applications involving high temperatures and corrosive environments. Their enhanced carbon content provides improved strength and performance at elevated temperatures, making them suitable for a range of industrial applications.

Alloy details of the product

304H stainless steel alloy has a carbon content of 0.04-0.10%, the alloy tends to provide much improved high temperature resistance when exposed to temperatures between 800 degrees F. The alloy. SS 304H has a shorter and longer creep strength than other alloys at temperatures in excess of 500 degrees Celsius and it has a very high resistance to sensitization. This is why this alloy is used in many industrial applications.

Manufacturing details of flanges

The production of 304H stainless steel flange is our industry only using high quality of the alloy. The raw materials we use are sourced only from trusted factories in the market and have been thoroughly tested and qualified for use in the development of flanges. The availability of professional professionals has greatly helped us in producing a top quality product that can be easily used in all industrial applications.
