Why Do Magnets Not Stick to My Stainless Steel Fridge?

Are you wondering why your magnets won’t stick to your stainless steel fridge? Don't worry, you're not alone. Many people have asked this same question and it's time for us to get to the bottom of it! Let's explore the science behind why fridge magnets don't always work on stainless steel surfaces and how we can still make them stick.

What is stainless steel and why does it not stick to magnets like other metals do?

Stainless steel is an iron alloy that contains at least 10.5% chromium which helps make the material extremely durable and corrosion-resistant.

On top of that, there is not just one variety of stainless steel. Different types vary in their composition, some containing more nickel than others, which can interfere with the magnetism of the surface. For example, 304 grade stainless steel contains 8-10% nickel and 18-20% chromium and will generally be slightly magnetic while 316 grade stainless steel contains 10-14% nickel and 16-18% chromium which makes it non-magnetic.

What makes stainless steel magnetic?

• Its iron content
• The alloy must be organized in either a martensitic or ferritic structure

How can I test if a magnet will stick to my fridge?

That's easy. For this purpose, we offer a custom sample pack. This includes 10 magnets with your printed design for just £9.

You can also have a look at our magnetic material data sheet for even more information on the type of magnet we use to create your fridge magnets.

Are you ready to become a collector of fridge magnets? It’s essential to understand the science behind magnetic materials before purchasing any product that claims to stick to stainless steel surfaces. Knowing the difference between magnetic and non-magnetic stainless steel grades will help you make a more informed purchase decision. If you have any questions, we are here for you.
