IF steel

IF steel: Flexible material for optimum formability

IF steels (interstitial-free) are specially treated steel grades characterised by very good formability and extremely low carbon content. This steel grade is preferred in the automotive industry, where the material must be deep-drawn in accordance with strength specifications.

Manufacture, grades and applications

IF steel is produced using a special manufacturing process in which carbon and nitrogen are removed from the steel. Materials such as these are normally contained in other types of steel and lead to increased strength of the steel, but at the expense of formability. With IF steel, the removal of these elements creates a material that is particularly easy to form.

Various grades are available, for example CR210IF or CR240IF, which differ in terms of strength and formability.

In the automotive industry, the steel is often used for the production of body parts such as doors, wings or bonnets.

What are the properties of IF steel?

IF (interstitial-free) steels are characterised by their special formability. They contain almost no carbon and nitrogen, which gives them high formability and ductility. These properties make them an ideal choice for applications that require high formability, such as in the automotive industry.

What does the grade mean for IF steel?

The grade of IF steel provides information about the specific properties of the material, such as its formability and carbon content. It is regulated by DIN standards. Common grades are CR210IF or CR240IF, for example.
