To strike iron in English is to forge it. This term comes from the process of shaping metal by heating it until it becomes pliable, and then pounding it with a hammer to shape it into a desired form. For example:

The blacksmith heated the iron in the forge, and then began to forge it into a sword.

The art of forging iron has been practiced for centuries, and is still used today in the creation of metal tools and objects.

The forge is the heart of the blacksmith's workshop, where iron is heated and shaped into various forms.
