We offer a large selection of SS 304H Pipes and Tubes in Seamless, Welded, SAW, LSAW, and DSAW, among other forms. These stainless steel 304L pipes and tubes are available in a variety of dimensional specifications to meet the needs of the customers and are renowned for excellent tensile and material strength. Widely used in machinery and utensils for the production and handling of food, drinks, and dairy products are SS 304H Stainless Steel Pipes & Tubes.

Stainless Steel 304H Pipes & Tubes are another type of stainless steel piping and tubing, specifically made from grade 304H stainless steel. Here’s some information about the content of Stainless Steel 304H:

  1. Grade: Stainless Steel 304H is an austenitic stainless steel grade that is a high-carbon variation of the widely used 304 grade.

  2. Chemical Composition: The chemical composition of Stainless Steel 304H typically includes the following elements:

    • Chromium (Cr): 18-20%
    • Nickel (Ni): 8-10.5%
    • Carbon (C): 0.04-0.10%
    • Manganese (Mn): 2% maximum
    • Silicon (Si): 0.75% maximum
    • Phosphorus (P): 0.045% maximum
    • Sulfur (S): 0.03% maximum
  3. High Carbon Content: Stainless Steel 304H has a higher carbon content compared to 304L. The increased carbon content provides improved high-temperature strength and creep resistance.

  4. Heat Resistance: Stainless Steel 304H exhibits excellent resistance to high-temperature environments, making it suitable for applications involving elevated temperatures and thermal cycling.

  5. Corrosion Resistance: Similar to 304L, Stainless Steel 304H also offers good corrosion resistance against a wide range of corrosive media, including oxidizing and reducing acids.

  6. Applications: Stainless Steel 304H Pipes & Tubes are commonly used in applications where high-temperature strength and corrosion resistance are required. Some typical applications include:

    • Heat exchangers
    • Boiler tubes
    • Refinery equipment
    • Power generation industries
    • Furnace parts and components
    • Chemical processing equipment
  7. Physical Properties: The physical properties of Stainless Steel 304H are similar to other austenitic stainless steels, including a density of 8.0 g/cm³, a melting point of 1400-1450°C, and a specific heat capacity of 500 J/kg·K.

It’s important to note that specific properties or requirements may vary depending on the manufacturer or specific product, so it’s always recommended to consult the manufacturer’s specifications for detailed information on Stainless Steel 304H Pipes & Tubes.
