What Is Stainless Steel?
Stainless steel is a type of steel that contains at least 10.5% chromium, which makes it highly resistant to corrosion. Chromium is a key element in stainless steel because it forms a thin layer of oxide on the surface of the metal, which protects it from further corrosion. Stainless steel is available in many different grades, each with slightly different compositions and properties. The grades of stainless steel used most often in sublimation are 304 and 316. 
How Does Sublimation Work?
Sublimation is a process where a solid material turns into a gas without going through the liquid phase. This can happen when the material is heated to its vaporization point and the pressure is released. When heat is applied to a solid material, the molecules of that material begin to move faster. If the heat is increased enough, the molecules will have enough energy to break apart the bonds that hold them together and they will turn into a gas.
Sublimation can also happen when a material is cooled down very quickly. This is because the molecules don’t have time to slow down and form new bonds as they cool. When this happens, the material goes straight from the gas phase to the solid phase without going through the liquid phase. 
Why Use Stainless Steel?
Stainless steel is a popular choice for sublimation because it is strong, durable, and corrosion-resistant. It is also easy to clean and maintain. Stainless steel can be used for a variety of applications, including cookware, kitchen appliances, and medical equipment.

How to Make Sublimation Coating for Stainless Steel?
Sublimation coating is a type of paint or coating that is specifically designed to allow sublimation inks to bond with the surface. Sublimation inks are a special type of ink that can be heat transferred onto a variety of surfaces, including stainless steel. In order for the inks to properly bond with the surface, the surface must first be properly prepared with a sublimation coating.
There are a few different methods that can be used to apply a sublimation coating onto stainless steel. One popular method is to use a spray-on sublimation coating. This type of coating can be easily applied using a standard aerosol pump sprayer. Another popular method is to use an airbrush to apply the coating. This method provides a more even coating, but can be more time consuming.
Once the coating has been applied, it needs to be cured. Curing can be done using a heat press or an oven.If using an oven, the coated stainless steel should be placed in the oven for 30 minutes at 400°F (204°C).
After the coating has been cured, it is now ready to have sublimation inks applied. The inks can be applied using a standard inkjet printer and sublimation paper. Once the inks have been applied, they need to be heat transferred onto the stainless steel. This can be done using a heat press or an oven. When using a heat press, the inked stainless steel should be placed on the heat press for 60 seconds at 400°F (204°C). If using an oven, the inked stainless steel should be placed in the oven for 2 minutes at 400°F (204°C).
Once the inks have been properly transferred, they will become permanent and will not fade or wash away. The sublimation coating will also help to protect the inks from scratching and UV damage.
How Do You Sublimate Stainless Steel In The Oven?
You can actually sublimate stainless steel in the oven, but you’ll need to purchase a specially made transfer paper that’s designed for this purpose. The process is pretty simple:
- Preheat your oven to 400 degrees Fahrenheit.
- Place your stainless steel item on the transfer paper.
- Place the transfer paper (with the stainless steel item) onto an oven-safe tray or cookie sheet.
- Put the tray or cookie sheet into the preheated oven and bake for 3-5 minutes.
- Remove from the oven and let cool completely before handling.
Your stainless steel item should now have a beautiful design that’s been permanently transferred!
Can You Do Sublimation On Stainless Steel Tumblers?
Yes, you can do sublimation on stainless steel tumblers! Stainless steel is a great substrate for sublimation because it doesn’t require any special coating – the ink will adhere directly to the metal. That said, there are a few things to keep in mind when working with stainless steel.
First, because the ink will be absorbed directly into the metal, the colors will not be as vibrant as they would be on other substrates. This is especially true for dark colors; white and light colors will still look good, but don’t expect them to “pop” like they would on a coated mug.
Second, stainless steel is a smooth surface, so you won’t get the same level of detail as you would with a coated substrate. This means that complex designs or very small text may not print well.
Third, stainless steel is a bit of a tricky surface to work with when it comes to sublimation. Because the ink is absorbed directly into the metal, it can be difficult to get an even coat of color. This can result in some areas being darker or lighter than others, or in streaking.
Fortunately, there are a few things you can do to minimize these issues. First, make sure your design is simple and that any text is large and easy to read. Second, use masking tape to cover any areas you don’t want to print (this will help prevent streaking). Finally, be sure to use an even, continuous printing motion when applying the ink to the stainless steel.
With a little practice, you’ll be able to produce great-looking stainless steel tumblers that are perfect for promotional events, gifts, or just everyday use! 
Alternatives to Stainless Steel for Sublimation
While stainless steel is the most commonly used metal for sublimation, it’s not the only option. Other metals that can be used for sublimation include aluminum, brass, and bronze. Each of these metals has its own benefits and drawbacks that should be considered before making a decision.It’s less expensive than stainless steel and has a lower melting point, making it easier to work with. Aluminum also provides a brighter and more vibrant image when sublimated. However, it is more prone to scratching and denting than stainless steel.
Brass and bronze are both more expensive than aluminum but offer a number of advantages. Both metals have a higher melting point than aluminum, making them more durable. Brass and bronze also create a more subtle image when sublimated, which may be preferred for some designs.
Finally, it’s important to note that not all metals are suitable for sublimation. Metals such as iron and steel will not work because they have too high of a melting point. Copper and its alloys are also not typically used for sublimation due to their reactivity with certain chemicals.
When choosing a metal for sublimation, it’s important to consider the benefits and drawbacks of each option. Stainless steel is the most popular choice but aluminum, brass, and bronze can also be used. Each metal has its own unique advantages and disadvantages that should be considered before making a decision.
If you’re looking for a more affordable option, aluminum is the way to go. For a more durable metal, brass or bronze might be a better choice. Ultimately, the best metal for sublimation is the one that meets your specific needs and preferences.
