Can Stainless Steel Be Used In A Microwave?

As a child, you were likely told that it is not safe to put metal in the microwave.

As a result, you might wonder if this is the case for all metals, such as stainless steel.

It is not safe to use stainless steel containers in the microwave, as this can be a serious fire hazard.

Microwaves are really useful devices for warming up food. Yet, their design means that only certain utensils can be used in microwaves.

You should look out for microwave-safe symbols. Unfortunately, not all products contain this information.

Luckily, we are here to answer any questions about the relationship between stainless steel and microwaves.

Can Stainless Steel Be Used In A Microwave?

Is It Okay To Put Stainless Steel In Microwaves?

Quick Answer: Can Stainless Steel Be Used In A Microwave? No, you must never put stainless steel in the microwave. Though some cooking utensils are made from stainless steel, this material is not microwave safe. This is because stainless steel is a reflective material. This results in the steel being unable to absorb microwaves like other materials are capable of doing. Not only will this mean that your food doesn’t get heated up, but the reflection of microwaves can damage your device.

Another reason why metal is a no-no for microwaves is that the material contains loads of electrons.

These electrons can be heated quickly, potentially causing the metal to explode or burn.

What Are The Consequences Of Putting Stainless Steel In A Microwave?

Aside from leaving your food cold, stainless steel could also affect its taste.

If you have accidentally put a stainless steel object in the microwave, it is best to avoid eating the food.

Though the food can be safe, it is not worth taking the risk.

This can also have far more hazardous and explosive consequences.

The metal can create sparks in the microwave, which can be quite dangerous.

Things can escalate, with the microwave potentially catching fire.

If you are unable to put the fire out, this can cause the whole kitchen to catch fire.

In this instance, your stainless steel utensil will likely have been burned.

In the worst cases, the microwave can even explode. If you are in close proximity to the microwave, you can receive severe burns.

While the microwave is not guaranteed to explode, it is not worth taking the risk. Even a thin sheet of stainless steel can be very unsafe.

Even if your microwave does not explode or start a fire, it will likely be damaged.

This will mean that you need to go through the hassle of buying a new microwave.

Additionally, this results in you spending more money on another appliance.

This is why it is recommended that you never put metal, such as stainless steel, in the microwave.

Will Stainless Steel Always Explode In A Microwave?

Can Stainless Steel Be Used In A Microwave?

No, stainless steel will not always explode. This will be reliant upon the type of utensil that you are using.

Flat or rounded stainless steel objects, such as spoons, are far less likely to explode than pointed or sharp items.

Thus, even a small metal nail can cause dire consequences in one of these mechanisms.

Things To Bear In Mind

Hopefully, this guide will have made you more knowledgeable about the dangers of using stainless steel in a microwave.

Though stainless steel will not always explode or cause fires, we do not think that the risk is worth it.

Therefore, you should remember the following to keep yourself safe when using a microwave:

  • Check to see if your dishes have metal trims. Even a little bit of metal can be hazardous, so you should not put a bowl in the microwave if it has a metallic trim. Unless the dish with metal trim has been designed for use in the microwave, you should refrain from microwaving them.
  • Ideally, you should keep stainless steel items away from the microwave, especially the walls. This could result in the creation of sparks, potentially causing a fire.
  • Remember to take metal cutlery out of a dish before you microwave it. It can be easy to accidentally leave a metal spoon in a bowl, but this could also result in fires.
  • While some sites maintain that it is acceptable to put a metal spoon in a microwave for a few seconds due to its rounded shape, we do not advise doing this. This is because you risk creating a fire hazard.
  • Always check to see whether or not a dish is microwave safe. You might assume that something can be used in one of these ovens. Yet, the manufacturer information might tell you otherwise.

What Materials Can Be Put In The Microwave?

Now that you know that stainless steel and other types of metal cannot be used in the microwave, you should think about what materials can be used. 

If you are unsure of whether a bowl or plate can be used in a microwave, your best bet is to check the reverse side.

Often, manufacturers will contain information about whether products are microwave safe on the base.

As a result, you can find out whether dishes are microwave and dishwasher safe.

In general, certain materials are usually microwave safe. This includes:

  • China
  • Pottery
  • Fine china (as long as it is not in there for too long)
  • Glass
  • Ceramic
  • Paper
  • Plastic
  • Cling film

How Do Microwaves Work?

Can Stainless Steel Be Used In A Microwave?

Created in 1945, microwave ovens are now essential parts of everyday life.

Most people have these cooking devices in their kitchens, using them to reheat food and drink.

As suggested by the name, microwave ovens use microwave frequency to heat food.

The oven generates microwaves via the magnetron. These microwaves will be absorbed by the food.

Specifically, the water molecules will be vibrated. This vibration will heat the food.

Consequently, foods with high quantities of water molecules will heat faster.

If you are looking for a quick method of reheating your food, then a microwave is an excellent choice.

What Are The Uses Of Stainless Steel?

Stainless steel is a very versatile material that has numerous uses.

There are lots of advantages to using stainless steel, such as its resistance to corrosion and heat.

Plus, it is a strong and durable material. This results in stainless steel having multiple uses. This includes:


Stainless steel is widely used in catering equipment. As mentioned, the material has heat resistance.

This makes stainless steel ideal for cooking utensils since they can still be used in high temperatures.

For instance, stainless steel can be used to construct anything from cutlery, to grills, to saucepans.

Stainless steel can also be used as a finishing material.

This gives products, such as fridges and dishwashers, extra protection and can enhance the aesthetics.


Stainless steel is being increasingly used in architecture. Only recently has it become widely used because it was quite expensive.

It can be used in architecture, namely to make bridges. Stainless steel is an outstanding option because of its strength.

Moreover, it can be used in the construction of buildings and other structures.

Medical Tools

Lots of medical tools can be constructed from stainless steel. It is a magnificent material to use because it will not corrode, even if it is exposed to high temperatures.

Furthermore, it can be easily molded into various shapes, allowing manufacturers to build a wide range of equipment.

Stainless steel is used to make medical equipment that comes into contact with chemicals and bodily fluids.

Offshore Technology

Lastly, stainless steel is also used in the construction of offshore materials. In particular, this material is used for piping.

These pipes are strong and durable

Ultimately, stainless steel has tons of uses thanks to its unique properties.

Yet, stainless steel items should not be placed in the microwave.

If you put this material in the microwave, you are putting not only yourself but also others in danger!
