SS201 and SS304 have both familiar properties, but there are also significant differences.
Introduction
Stainless steel is one of the most common materials found in modern kitchen and home furnishings. Due to its versatility and durability, stainless steel is regularly used in many household and commercial items, such as appliances, cookware, kitchen utensils, wall coverings, window frames, door handles, and more. But not all stainless steel is the same, and two of the most commonly used types are SS304 and SS201. While both steels offer excellent durability and wear-resistance, there are a few key differences between the two that can help you decide which one is best for your needs.
Composition
SS201 is a lower cost alternative to stainless steel 304, and it is generally used in lighter-duty structures. It is composed of 17- percent chromium, 4- percent nickel, 8-percent manganese and 6-percent nitrogen, with the remainder made up of carbon and other trace elements. It offers excellent formability and weldability, but it is only moderately resistant to corrosion.

It offers excellent formability and weldability, but it is only moderately resistant to corrosion.
On the other hand, SS201 is a lower grade of stainless steel that has less chromium and nickel than SS304. This makes it less resistant to corrosion and staining, but also slightly less expensive. While SS201 may not be able to withstand as much wear and tear as SS304, it is still a very strong and durable material and can be suited to many everyday home and business needs.
Corrosion Resistance
SS201 is not as corrosion resistant as SS304. This is because the composition includes less chromium, which provides the metal with passivation (corrosion protection) properties. Additionally, SS201 is more susceptible to attack from certain acids and alkalis.
In comparison SS304 has superior corrosion resistance due to its greater chromium content. It is less susceptible to acids and alkalis, and as such it is more suitable for food processing and medical applications where corrosion resistance is critical.
To determine whether SS304 or SS201 is the best choice for your needs, it’s important to consider the level of wear, staining, and corrosion resistance that you require. For example, if you are shopping for stainless steel handles for kitchen drawers, SS304 might be the better option since it has superior corrosion resistance and can better handle the moisture in kitchens. Likewise, for items that will be used outdoors, such as window frames or door handles, SS304 is likely the better choice for its superior strength and resistance to the elements.
Heat Resistance
201# can be used in temperatures up to 300°C (572°F). It is suitable for applications where temperatures don’t far exceed that such as petrochemical, dairy, and general manufacturing.
304# can be used in temperatures up to 800°C (1472°F). It is ideal for applications with higher temperatures. It is commonly used in the aerospace and automotive industries, and is suitable for applications such as nuclear power plants and fuel burners.
Cost
201# is a lower cost alternative to 304#, as it is less expensive to produce. Depending on the application, one may be better suited than the other in terms of cost.
In Conclusion
SS201 and SS304 are two popular grades of stainless steel. They both offer excellent formability and weldability, but SS304 has the superior corrosion resistance. Additionally, SS304 is better suited for higher temperature applications, whereas SS201 is more affordable. It is important to consider the advantages and limitations of both grades to determine which is the best option for a given application.
Ultimately, both SS304 and SS201 offer excellent strength and durability, and either one can be a great choice for most home and business needs. Just remember to consider the level of wear, staining, and corrosion resistance you require before you make a final decision. With the right steel selection, you can find the perfect stainless steel solution to suit your needs.
