Can You Laser Engrave Stainless Steel?

Yes, you can engrave stainless steel using a laser machine. The laser beams are powerful enough to engrave the material or object, but this engraving is not very deep, which is why it is often called laser etching.

Laser Etching Stainless Steel

When the laser beams react with the surface of the stainless steel, the temperature of the material increases rapidly and reaches the melting point of the material. After that, you see the marks on the surface. 

This temperature only melts the surface of stainless steel, but it is not enough to evaporate it because it is not at the boiling point.

Can You Oxidize Stainless Steel Using Laser 

A powerful laser can also oxidize the metal surface in no time. Due to oxidation, the metal is etched with a certain color. Usually, you see black markings on metals, but if the laser is powerful enough and it can oxidize the material with perfection, you see a wider range of colors that make etching or marking more beautiful.

On stainless steel, there is no need for pretreatment. You can get visible marks on the surface, but if you want to get darker marks, it is better to use a special compound. Usually, it is called metal marking spray. A thin and even coat of spray is applied to the metal. After that, the laser beams react with this compound and leave a darker mark that is more visible.

Many applications required stainless steel engraving. The most common is the marking of barcodes, company names, tags, and other things. Other than that, it is also used to create designs on various objects. For instance, you can laser engrave a stainless-steel tumbler for customization. 

What Kind of Laser Can Engrave Stainless Steel?

It is a must to know the right laser for stainless steel engraving before you buy one or test it out. There are various types of laser engraving machines available, but not all of them offer the best results. Each machine has its pros & cons.

The laser engravers that can engrave stainless steel are,

  • Fiber Laser 
  • Diode Laser
  • CO2 Laser
  • Infrared Laser 

Fiber Lasers

Fiber laser is the most preferred option when it comes to laser engraving stainless steel. The first reason behind its phenomenal performance is the wavelength of the laser. 

The commonly available fiber lasers have different wavelength ranges from 780nm to 2200nm. The wavelength depends on the doping of the core, which is done according to the application of the laser.

The wavelength of a fiber laser can be absorbed by metals, including stainless steel. Therefore, it can easily engrave or etch the material. Due to this, they are usually used for large-scale businesses.

The optical power of fiber lasers varies from 20W to several thousand watts, depending on the application. Some lasers can even cut various materials. But as far as the engraving of stainless steel is concerned, small fiber lasers of 20-100W are also suitable.

The engraving results of a fiber laser are exemplary. With only one pass, the engraving is quite clear and visible compared to other types of laser machines. The best part is that there is no need for any pretreatment.

Diode Lasers

A diode laser engraver is not as powerful as a fiber laser, but it can still etch stainless steel and make the marks you want. It is usually a blue laser, which has a wavelength of 450-455nm.

This wavelength can also be absorbed by stainless steel, but you don't get dark etching results in one pass. You might need to have two or more passes without pretreatment. However, it is better to apply marking spray and etch the metal in one go.

Keep in mind that the results depend on the optical power of the laser. The commonly available 10W laser machines require more passes. But if you have got a 20W laser machine, it can easily engrave in one pass. But again, using metal marking spray is quite beneficial for achieving phenomenal results.

CO2 Lasers

A CO2 laser is also a good option that can be used to engrave on stainless steel. These lasers are more powerful than diode lasers but still lesser than fiber lasers. However, they can engrave steel with perfection.

CO2 lasers have a much higher wavelength than other types of lasers we have discussed. It is usually 10,000nm. However, it can also be absorbed by some metals, including stainless steel. The important thing about C02 lasers is their power. They usually have a 40W or higher optical power, which is good for engraving stainless steel at a better speed.

Similar to diode lasers, CO2 lasers also require pretreatment for better results. You can use a marking spray to etch the surface of the material. You can also try without marking spray, but the engraving will be a bit light.

Infrared Lasers

Infrared laser (IR laser) is another type of laser you can use for stainless steel and other metal engravings. It is also a kind of diode laser, but its wavelength is quite higher than blue lasers. 

The main purpose of this laser is to engrave metals, especially precious metals such as gold, silver, and platinum. However, it can also engrave other metals, such as stainless steel, copper, aluminum, and titanium.

The result for metal engraving is excellent. It is because the 1064nm laser beams are easily absorbed by metals. Therefore, you see clear, clean, and visible results without any pretreatment. Other than metals, these lasers are also excellent for plastic engraving and cutting.

5 Best Practices for Laser Engraving Stainless Steel

If you are new to engraving stainless steel using a laser machine, you should look at these tips and best practices. These will bring perfection to your work and make it easier.

Clean the Surface

Cleaning the surface of stainless steel is very important, and people usually ignore it. There can be dust, grease, and other particles that can create a hindrance for the laser. Therefore, you must clean the material first before engraving it.

Cleaning is pretty simple. You need rubbing alcohol and a soft cloth. Clean the surface of the metal, and then it will be ready for engraving.

Adjust the Focus

Without the optimal adjustment of the focus, you won't get the best results. The laser cannot perform or engrave the material if it is not focused properly. You won't get a better contrast, or you might need to run more passes.

Therefore, make sure to adjust the focus in the first place before you start engraving. It is a must for every material.

Power-Speed Test

You cannot guess the right power and speed required to engrave an object or material. Therefore, you must do a power-speed test. It will tell you the right power and speed combination.

For stainless steel, it is recommended to engrave on high power and low speed. It will give you a better contrast. But when you do a power-speed test, you get a complete idea of the power and speed you need to select.

Moreover, some laser engravers produce various colors on different power and speed settings. With the help of the power-speed test, you get to know about the exact settings to achieve the desired color.

Apply Laser Marking Spray

Laser marking spray saves you from multiple passes. If you are using a suitable laser engraving machine, then one pass will be enough, along with the laser marking spray. With xTool D1 Pro 20W, you get phenomenal results in one pass, and there is no need to run more passes.

The spray is cleaned easily, so you don't have to worry about it. You can remove it using water and a cloth.

Try on a Cheap and Spare Material

Many times, people mess up with laser engraving. Due to wrong decisions and practices, they end up wasting the object they are engraving. Sometimes, the object is precious, and you cannot take any risk.

It is better to try on a cheap or extra material before engraving the real object. You can take a piece of cheap stainless steel and then try engraving it. It will save you a lot of time and money.
