304H Stainless Steel Round Bar vs 304 Stainless Steel: What’s the Difference?

When selecting stainless steel for your project, understanding the differences between 304H stainless steel and 304 stainless steel is essential. While both are highly versatile and widely used in many industries, they have distinct properties that make them better suited for different applications. In this post, we'll break down the differences between 304H round bars and 304 stainless steel, and how these differences can affect your choice of materials.

What is 304H Stainless Steel?


304H stainless steel is a high-carbon version of the standard 304 stainless steel. The addition of carbon in 304H round bars improves its strength, especially at elevated temperatures. This makes 304H round bars ideal for high-temperature applications like boilers, pressure vessels, and heat exchangers.

What is 304 Stainless Steel?


304 stainless steel is the most common type of stainless steel. It is an austenitic steel alloy that offers excellent corrosion resistance and formability. However, 304 stainless steel is not as strong as 304H stainless steel at higher temperatures. It is best suited for general-purpose applications like kitchen equipment, storage tanks, and architectural structures.

Key Differences Between 304H and 304 Stainless Steel



  1. Carbon Content:
    The most notable difference between 304H round bars and 304 stainless steel is the carbon content. 304H has a higher carbon percentage, typically ranging from 0.04% to 0.10%, compared to the lower carbon content in 304 stainless steel (less than 0.08%). This increased carbon content enhances the strength of 304H round bars, especially at high temperatures.

  2. Temperature Resistance:
    Because of the higher carbon content, 304H round bars perform better under high heat. They can withstand temperatures up to 1,200°F (650°C) without compromising their strength. On the other hand, 304 stainless steel begins to lose its strength at temperatures above 800°F (427°C), making it less suitable for high-temperature environments.

  3. Strength:
    The increased carbon content in 304H round bars provides greater tensile strength compared to 304 stainless steel. This makes 304H round bars more suitable for applications that involve high-pressure or high-temperature environments, while 304 stainless steel is ideal for standard, low-pressure applications.

  4. Corrosion Resistance:
    Both 304H round bars and 304 stainless steel offer excellent resistance to corrosion. However, 304 stainless steel is more resistant to corrosion in many standard conditions, as it has lower carbon content and fewer impurities. 304H round bars might be more susceptible to corrosion in certain environments, but they remain highly resistant to oxidation and rust.


Applications of 304H Stainless Steel vs 304 Stainless Steel


304H round bars are primarily used in applications requiring high strength at elevated temperatures. These include:

  • Boilers and Pressure Vessels

  • Heat Exchangers

  • Turbine Blades

  • Welding Components for High-Temperature Environments


304 stainless steel is more commonly used in general applications, including:

  • Kitchen Equipment

  • Storage Tanks

  • Architectural Structures

  • Food Processing Equipment
