How can you cut stainless steel?

Sawing or cutting stainless steel is not without its problems. In principle, stainless steel can be cut by machine or manually like any other steel, but you can quickly reach your limits. Choosing the right tools and tools is extremely important. Below we will show you how you can also cut stainless steel to a certain extent.

How stainless steel is cut in a specialist workshop

Stainless steel is a product that first impresses with its special purity and generally high hardness. In addition, this hardness can be improved over different alloys, as well as many other stainless steel properties. Usually, the following machines and tools are used or applied for cutting and sawing stainless steel:

  • Plasma cutting
  • Water cutting
  • Laser cutting

However, very few DIY enthusiasts will have a plasma cutter, let alone machines for water or laser cutting of stainless steel.

Home improvement for cutting stainless steel

You can cut stainless steel to a certain extent, but also with conventional machines and tools. Especially products like stainless steel tubes or stainless steel profiles have to be cut to size again and again.

To be able to separate such workpieces, you need a powerful machine for sawing or cutting. Basically, you can separate stainless steel with a circular saw or even a jigsaw. However, as already mentioned, the device must be powerful.

Requirements for saw blades and saw

The saw blades must be made of HSS steel. Conventional saw blades are not grown stainless steel. In addition, the teeth are important. For stainless steel sheets with small wall thicknesses, the teeth should be as fine as possible. The speed of the machine may be slightly higher at the same time. Still, she should not be too high. We will explain more about the speed and feed in the further course of the text.

Speed ​​and feed during cutting

For full-volume workpieces, the toothing should be selected to the contrary, that is, as coarse as possible. The speed is here also set rather low. In addition, however, the feed is to be adapted when cutting or sawing sheets as well as full workpieces. Under no circumstances should this be too high.

Cutting oils for cooling the interface

In addition, due to the massive hardness of stainless steel also generates more heat. Therefore, the use of a coolant is strongly advised. Suitable cutting oils are suitable. In the case of the overall (compared to other materials) low speed and the significant feed, the machine used must withstand this load. Cheap appliances overheat in no time and are then ready for disposal. Unbedingt It is essential to observe the following when cutting stainless steel

In addition, you must take into account the special features between alloyed and unalloyed stainless steels. Alloys are usually also responsible for a significantly higher strength of the steel. Depending on the alloy, it may even be that, despite this high quality finish, you can not separate the existing stainless steel workpiece. Then only the way to the specialist company remains.

If the high quality and high quality of your stainless stainless steel workpiece are also crucial, you must never use release agents that have already been used to cut stainless steel. Rost Stainless steel may rust as well

In the later grinding of stainless steel, the high proportion of chromium (equal to or greater than 10.5 percent) creates a so-called passive oxidation layer. This chromium-based layer is responsible for ensuring that stainless steel does not rust. Immer Always store and process stainless steels separately

This does not mean, however, that stainless steel could not rust. In particular, when the surface has been contaminated by particles of stainless steel, they begin to rust and continue to corrosion the entire workpiece. Therefore, stainless and rusting steel must not be stored in the same rooms. Tools or release agents that have already been used to cut stainless steel must not be used.
