How to stop pushing wedges and irons

Grinding iron

Grinding iron for various reasons

If you want to work iron with certain techniques, you have to prepare it. For example, before you solder or weld iron. You have to grind it bare. But it can also be used to polish it afterwards and to smooth the surface accordingly.

Iron is not just iron

However, not all iron is the same. Although it is the fourth most common element after oxygen, aluminum and silicon, you will only have it in its pure form for processing in very rare forms. The typical forms in which iron occurs would be:

  • Pure form
  • Raw or cast iron (high carbon content, therefore cannot be deformed or forged)
  • as wrought iron with a low carbon content and thus malleable
  • as an alloy component of a steel or stainless steel

Cast and wrought iron and iron alloys

In its pure form, iron is used for magnets. Otherwise, cast iron and wrought iron are the two most important basic shapes. In addition, iron is usually just one of many components in an alloy. This means that the properties differ significantly. Wrought iron is also often an alloy.

Even with steels there are clear differences

But there are already considerable differences in the colloquial distinction between steel and stainless steel. A steel can be alloyed in a more noble or less noble manner. This is particularly evident in the example of stainless steel. If you want to grind stainless steel, you have to use grinding tools that have never been used for any other steel.

Make sure the tool is clean when sanding

If, for example, you were to use a wire brush with a trim made of conventional steel wire, this could soon lead to corrosion on the brushed stainless steel. This of course also applies to sandpaper and other sanding utensils.

Even storing steel and stainless steel together is problematic

So you always have to determine exactly in which form the iron to be processed is available to you. In this context, also keep in mind that you have to store different steels and stainless steels separately in order to prevent a chemical reaction in the form of oxidation.

Iron, in particular, is known for the fact that it begins to corrode quickly when it comes into contact with water and oxygen, i.e. even in normal air with normal humidity. You have to protect the ground iron workpiece against corrosion after grinding. To do this, you can galvanize the iron. Priming and painting the iron would also be an option.
