06Cr19Ni10 vs 304 Steel – What’s the Difference

06Cr19Ni10 vs 304 Steel

When it comes to stainless steel, many different grades are available on the market, each with its own unique set of properties and characteristics. Two of the most popular grades of stainless steel are 06Cr19Ni10 and 304, but many people may need to learn the difference between them. In this article, we’ll break down the differences between the two types of steel and what sets them apart.

What is 06Cr19Ni10 Steel?

06Cr19Ni10 is an austenitic stainless steel grade. It contains 19% Chromium, 10% Nickel, and 6 % Chromium as major alloying elements. It has excellent corrosion resistance properties, allowing it to be used in harsh environments where other materials fail quickly. Its high creep strength makes it useful for high-pressure applications, such as pressure vessels and boilers. This grade can also be used for manufacturing consumer products like kitchen utensils or automotive parts due to its good mechanical strength and ductility.

What is 304 Steel?

304 Steel is an austenitic stainless steel grade that is one of the most widely used and versatile. It offers good corrosion resistance to many environmental conditions, high strength and excellent formability. It has high chromium content (which provides corrosion resistance) and low carbon content for better welding performance. With its superior durability, this steel is often used for medical equipment, kitchenware, automotive parts, and architectural panels, among many other applications.

Difference Between 06Cr19Ni10 and 304 Steel

Chemical Composition

06Cr19Ni10 is a high-quality austenitic stainless steel. Its chemical composition includes 18% chromium and 8% nickel, making it highly resistant to corrosion and rust. The carbon content in 06Cr19Ni10 is less than 0.08%, which results in excellent weldability and structural stability. On the other hand, 304 is also an austenitic stainless steel that contains 18% chromium and 8% nickel, but it also includes a small amount of carbon (0.08%). This small amount of carbon helps to improve the material’s strength and hardness.

Mechanical Properties

Regarding mechanical properties, 06Cr19Ni10 has a higher tensile strength than 304, making it more durable and resistant to wear and tear. The yield strength of 06Cr19Ni10 is also higher than 304, meaning it can handle higher loads and is more deformation-resistant. However, 304 stainless steel exhibits better ductility, making it easier to form and shape.


Due to its higher strength and toughness, 06Cr19Ni10 is commonly used in applications where durability is critical, such as construction, chemical processing, and marine engineering. 304 stainless steel is commonly used in household appliances, kitchen equipment, and automotive parts, where corrosion resistance is more important than strength.

Surface Finish

Both materials can be finished with a high degree of polish, but 304 stainless steel typically has a better surface finish, making it more aesthetically pleasing. This is because the additional carbon in 304 allows for better tooling, which results in a smoother surface compared to 06Cr19Ni10.


While 06Cr19Ni10 and 304 stainless steel are high-quality materials, the price of 06Cr19Ni10 is generally higher than 304. This is because 06Cr19Ni10 is less commonly used in most applications, and the additional nickel and molybdenum content increases the cost of manufacturing.


In conclusion, 06Cr19Ni10 and 304 stainless steel are two popular austenitic stainless steel grades with varying chemical compositions, mechanical properties, and applications. While 06Cr19Ni10 is stronger and more resistant to wear and tear, 304 is more ductile and has better corrosion resistance. Choosing the right type of steel for your application will depend on your specific requirements for strength, corrosion resistance, and finish. By understanding the differences between the two materials, you can make a more informed decision when choosing the right stainless steel for your needs.
