Stainless Steel 304 vs 202 – What’s the Difference

Stainless Steel 304 vs 202

When choosing the right material for your next project, it’s essential to understand the differences between different types of stainless steel. Stainless steel 304 and 202 are two of the most commonly used types of stainless steel, and they have some significant differences that can impact your decision-making process. In this post, we will discuss the differences between stainless steel 304 and 202 so you can decide which one is right for your project.

Difference Between Stainless Steel 304 and 202


One of the primary differences between 304 and 202 stainless steel is their composition. Stainless steel 304 contains 18% chromium and 8% nickel, while stainless steel 202 contains only 17% chromium, 4% nickel, and 0.3% nitrogen. This difference in composition affects the steel’s performance in various conditions, making stainless steel 304 more suitable for certain applications than stainless steel 202.

Corrosion Resistance

Stainless steel is known for its corrosion resistance, and both 304 and 202 have excellent corrosion resistance properties. However, due to its higher nickel content, stainless steel 304 is more corrosion-resistant than stainless steel 202. This makes stainless steel 304 ideal for use in environments exposed to high moisture levels or corrosive substances, such as marine applications.


Stainless steel 304 is known for its superior strength to stainless steel 202. Due to its higher nickel and chromium content, stainless steel 304 has a higher tensile strength and can withstand more stress and pressure than stainless steel 202. This makes stainless steel 304 a better option for heavy-duty applications, such as construction and structural engineering.


Weldability is another factor when choosing between stainless steel 304 and 202. While both types of stainless steel are weldable, stainless steel 202 is easier to weld than stainless steel 304. This is because stainless steel 202 has a lower carbon content, making it less prone to sensitization and easier to weld without causing damage to the material.


Finally, cost is another factor to consider when choosing between stainless steel 304 and 202. Stainless steel 202 is less expensive than stainless steel 304, making it a more economical option for some projects. However, if you require superior strength, corrosion resistance, and durability, stainless steel 304 may be the better investment in the long run.


Choosing between stainless steel 304 and 202 depends on your specific project needs. If you prioritize corrosion resistance, strength, and durability, stainless steel 304 may be your best option. However, if cost is a significant concern, or if you need a material that is easier to weld, stainless steel 202 may be the right choice. By understanding the differences between these two types of stainless steel, you can make an informed decision and choose the best material for your project.
