There are various reasons why it may be necessary to cut steel, and there are different types of steel depending on their carbon content (austenite, ferrite, martensite). You can have pieces of steel of various shapes and thicknesses, such as a tube, sheet, bar, wire or rod. This article focuses on steel sheets.
Steps
Step 1. Decide if you need stainless steel or mild steel for your project
The second rusts quickly, while the first is corrosion resistant.
Step 2. Evaluate if the job requires steel to harden
Mild steels with a high carbon content (about 1, 2%) are excellent for hardening. If you use stainless steel, try martensite or the 400 series
Step 3. Determine the thickness of the steel sheet
This value is usually referred to as "gauge." The higher the value, the thinner the thickness.
Step 4. With a permanent marker, outline the section you need to cut
If you are unsure of the shape and size you need, you should first use a template from another material. If the prototype works, then you can recreate the shape from the steel sheet. In case there are any corrections and changes to be made, move accordingly
Step 5. Cut the steel using the tool of your choice
There are many tools available, if the sheet is thin (like an 18 gauge) tinsmith scissors may be sufficient. A cutting table is useful for all types of slabs, and you find them available in two versions: for straight cuts and for curved machining. The first type allows you to cut steel in a straight line and in external curves, while the second is useful for more complicated processes. You can also use a hacksaw or shears, but be aware that you will have to work a lot to finish the edges
Warnings
- You have to sand the cut edges to make them safe to handle. You can use a belt grinder, file, or other abrasive tool. Always wear eye and ear protection.
- Remember that the cut edges of steel are always sharp regardless of the technique you used, so handle them carefully. Wear gloves when performing these steps.
