Is 321 Stainless Steel Magnetic?

When choosing a suitable material for a project, there are many things to consider. One of the most important is whether the material you select is magnetic. If it is, it can affect how your project works and create problems. In this blog post, we’ll discuss whether or not 321 stainless steel is magnetic and why that matters.

321 stainless steel is a type of austenitic stainless steel that contains titanium as an alloying element. It’s often used in high-temperature applications because of its oxidation resistance. But what about its magnetic properties? Is 321 stainless steel magnetic?

The answer is no—while most types of austenitic stainless steel are non-magnetic, some can be slightly magnetic due to their composition, but this isn’t true for all alloys. While 321 stainless steel does contain some ferrite content, it isn’t enough to make it a magnetically attractive material. That means that if you’re looking for a material that won’t be affected by magnets, then 321 stainless steel could be a good choice for your project.

In addition to being non-magnetic, 321 stainless steel has several other advantages over other materials, including good cold working characteristics and weldability. Its superior corrosion resistance also makes it suitable in harsh environments like chemical processing plants and other areas where exposure to corrosive substances is common.


When selecting materials for your project, it’s important to consider whether or not they are magnetic—especially if your application requires precision or accuracy that could be compromised by accidental magnetism interference. Thankfully, 321 stainless steel is non-magnetic, so you can rest assured knowing that magnets will not affect its performance or accuracy in any way. Plus, with its superior corrosion resistance and ability to withstand high temperatures, 321 stainless steel offers plenty of other benefits too! So if you’re looking for a material that won’t be affected by magnets but still provides excellent performance characteristics when exposed to extreme temperatures and conditions, then 321 stainless steel could be the perfect choice for you!
