Hey there! As a supplier of UNS S17400 sheets, I often get asked about the size range of these sheets. So, I thought I'd write this blog to give you all the deets.
UNS S17400, also known as 17 - 4 PH stainless steel, is a precipitation - hardening stainless steel. It's got some great properties like high strength, good corrosion resistance, and it's pretty easy to fabricate. That's why it's used in a bunch of industries, from aerospace to chemical processing.


Let's start with the thickness of UNS S17400 sheets. The thickness can vary quite a bit. Generally, you can find sheets with a thickness as thin as 0.01 inches (about 0.25 mm). These thin sheets are great for applications where you need a lightweight yet strong material, like in some electronic components or small - scale precision parts.
On the other end of the spectrum, the thickest UNS S17400 sheets can go up to around 2 inches (about 50.8 mm). These thick sheets are used in heavy - duty applications such as construction of large machinery parts or structural components where high strength is crucial.
Now, talking about the width of these sheets. The typical width range starts from around 12 inches (304.8 mm). This narrower width is useful for applications where you need to cut or roll the sheet into specific shapes without a lot of waste. For example, in the production of small - diameter tubes or narrow strips for various industrial uses.
The maximum width of UNS S17400 sheets can reach up to 72 inches (1828.8 mm). These wide sheets are ideal for large - scale projects like the construction of big storage tanks or large panels in industrial buildings. They reduce the number of joints and seams, which can enhance the overall integrity of the structure.
In terms of length, the shortest sheets are usually around 24 inches (609.6 mm). These shorter lengths are handy for prototyping or small - batch production. You don't have to buy a large quantity at once, which can save you some money if you're just testing out a new design.
The longest sheets can be up to 144 inches (3657.6 mm). These long sheets are used when you need a continuous piece of material, like in the manufacturing of long - span beams or long conveyor belts.
It's important to note that these are just general size ranges, and as a supplier, I can often work with you to get custom - sized sheets. If you have a specific project with unique size requirements, don't hesitate to reach out.
When comparing UNS S17400 with other stainless steels, it's interesting to look at some similar alloys. For example, Stainless Steel 317 / UNS S31700 / 1.4449 is another popular stainless steel. It has excellent corrosion resistance, especially in harsh chemical environments. However, its size range might be a bit different from UNS S17400, depending on the manufacturing processes and market demand.
Stainless Steel 321H / UNS S32109 / 1.4878 is known for its good resistance to intergranular corrosion at high temperatures. The size availability of this alloy can also vary, and it might be more suitable for high - temperature applications compared to UNS S17400.
Stainless Steel 316L / UNS S31603 / 1.4404 is one of the most widely used stainless steels. It has a broad size range as well, but its properties are different from UNS S17400. It's more focused on general corrosion resistance in a wide variety of environments.
The size range of UNS S17400 sheets gives you a lot of options for different applications. Whether you need a thin, narrow sheet or a thick, wide one, there's likely a size that will fit your needs. And if not, we can work together to get you the custom - sized sheets you require.
If you're in the market for UNS S17400 sheets, I'd love to have a chat with you. Whether you're a small - scale manufacturer or a large - scale industrial company, I can help you find the right size and quantity of sheets for your project. Just reach out, and we can start the conversation about how to meet your specific requirements.
