Composition and Properties: Stainless Steel 304H is an austenitic stainless steel, a modification of the well-known 304 grade. The "H" stands for high carbon content, which is typically between 0.04% and 0.10%. This increased carbon content provides improved high-temperature strength, making it suitable for applications involving elevated temperatures. In addition to carbon, 304H contains chromium, nickel, and small amounts of other elements. This composition gives it remarkable corrosion resistance, making it ideal for harsh environments, including those with exposure to acids and chemicals.

Strength and Durability: The elevated carbon content in 304H enhances its mechanical properties, making it stronger at higher temperatures. This characteristic is particularly valuable in applications such as industrial furnaces, where the material needs to withstand extreme heat and mechanical stress. The improved strength also allows for thinner sections and reduced material weight without sacrificing performance, making it an economical choice.

Corrosion Resistance: One of the most notable features of Stainless Steel 304H is its resistance to corrosion. It is highly resistant to a wide range of corrosive substances, including acids, alkaline solutions, and chloride-containing environments. This corrosion resistance makes it an excellent choice for applications in chemical processing, pharmaceuticals, and the food and beverage industry, where hygiene and product purity are crucial.

Fabrication and Machinability: Stainless Steel 304H round bars are readily fabricated and machined. They can be welded, forged, and formed into various shapes and sizes to meet specific project requirements. Their ease of fabrication and machinability allows for cost-effective manufacturing processes and customization.
