What is the Difference Between 304 and 202 Stainless Steel?

The main difference between 304 and 202 stainless steel lies in their composition, particularly their nickel and chromium content. Both are austenitic, non-magnetic stainless steels, but they have distinct properties and applications.

Composition:
304 stainless steel typically contains 8% nickel and 18% chromium.
202 stainless steel has around 4-6% nickel and 16% chromium.
Corrosion Resistance:
304 stainless steel offers excellent corrosion resistance due to its higher nickel and chromium content.
202 stainless steel has lower corrosion resistance compared to 304, as it has less nickel and chromium.
Strength and Toughness:
Grade 202 stainless steel has high toughness at low temperatures.
Applications:
304 stainless steel is widely used in commercial applications, food processing equipment, and large-scale industrial equipment, particularly in industries such as milk processing, beer brewing, and winemaking.
202 stainless steel is a more economical option for regular kitchen equipment, utensils, or sinks, due to its lower nickel content.
Cost:
304 stainless steel is generally more expensive than 202 stainless steel due to its higher nickel content.
202 stainless steel is a more cost-effective option for applications where high corrosion resistance is not required.

In summary, 304 stainless steel is characterized by its higher nickel and chromium content, offering excellent corrosion resistance and strength. It is widely used in commercial and industrial applications. On the other hand, 202 stainless steel has lower nickel and chromium content, making it more prone to rusting and less suitable for high corrosion resistance applications. However, it is a more cost-effective option for regular kitchen equipment and utensils.
