Stainless Steel 304 vs 310- What’s the Difference

Stainless Steel 304 vs 310

When choosing the right type of stainless steel for your project, you must know the differences between the various available grades. Two of the most commonly used grades of stainless steel are 304 and 310. While they may look similar, these two grades have several differences that could impact your choice. This blog post will explore the differences between Stainless Steel 304 and 310.

Difference Between Stainless Steel 304 and 310

Chemical Composition:

The major difference between Stainless Steel 304 and 310 is their chemical compositions. Stainless Steel 304 contains chromium-nickel content and low carbon, whereas Stainless Steel 310 contains higher quantities of nickel, chromium, and copper. Due to their different chemical compositions, these steels have different mechanical properties, corrosion and heat resistance.

Corrosion Resistance:

Generally, the Stainless Steel 304 and 310 have good resistance to corrosion in most environments. However, Stainless Steel 310 is more resistant to high-temperature oxidation and acid-based corrosive environments than 304. Stainless Steel 310 is thus commonly used in high-temperature applications like furnaces, engine parts, and aircraft.

Heat Resistance:

Stainless Steel 310 offers better heat resistance than Stainless Steel 304 due to its higher levels of chromium and nickel. Stainless Steel 310 maintains its strength and mechanical properties even in extremely hot temperatures of up to 1093°C. In contrast, Stainless Steel 304 cannot withstand the same temperatures, limiting its use in high-temperature applications.


Stainless Steel 304 is commonly used in food processing equipment, kitchen appliances, and architectural trim. It is also used in chemical industries and building facades due to its corrosion-resistant properties. On the other hand, Stainless Steel 310 is more commonly used in high-temperature applications, including furnace parts, heat treatment equipment, and gas turbines. Its corrosion resistance properties make it ideal for use in aggressive, acidic environments in the chemical industry.


The price of Stainless Steel 310 is higher than that of Stainless Steel 304 due to its higher nickel and chromium content. This price difference is understandable, considering that Stainless Steel 310 has improved heat and corrosion resistance properties, making it a more robust material that can withstand extreme conditions.


In summary, the differences between Stainless Steel 304 and 310 are primarily due to their chemical composition and resulting properties. While Stainless Steel 304 is more commonly used due to its affordability, corrosion resistance, and ease of fabrication, Stainless Steel 310 is a better option for applications requiring high-temperature and corrosion resistance to acid-based environments.
