304H Stainless Steel Tubes Supplier and Exporter | UNS S30409, SUS 304H & EN 1.4948 | Leoscor Alloy Pipes
304H Stainless Steel Tubes are high-carbon austenitic stainless steel tubes designed for applications requiring improved strength, durability, and performance at elevated temperatures. These tubes offer excellent resistance to oxidation, corrosion, and high-temperature conditions, making them suitable for demanding industrial environments.
Leoscor Alloy Pipes is a trusted supplier, stockist, and exporter of SS 304H Tubes, providing high-quality seamless and welded tube solutions for industries such as chemical processing, power generation, petrochemical, food processing, and industrial engineering.
304H Stainless Steel Tubes are a high-carbon version of 304 stainless steel tubes developed for applications where better creep strength and high-temperature performance are required. The higher carbon content improves strength retention during prolonged exposure to elevated temperatures.
These tubes contain chromium and nickel as major alloying elements, providing good corrosion resistance, oxidation resistance, and durability. Compared with standard 304 stainless steel tubes, 304H Tubes are preferred for high-temperature applications where additional strength is required.
304H Stainless Steel Tubes are commonly used in heat exchangers, boilers, refineries, pressure vessels, power plants, and chemical processing equipment. They are available in seamless and welded forms with different sizes, wall thicknesses, finishes, and shapes as per industrial requirements.
Equivalent Names of 304H Stainless Steel Tubes
The grade is internationally identified through different designations including UNS S30409 Tubes and SUS 304H Tubes. According to standard material designation systems, 304H stainless steel corresponds to UNS S30409 and SUS 304H designations.
