Given the wide range of stypes of steel available on the market, a great many norms and regulations have come into existence which can vary from country to country.

In Spain, steel types are classified according to the norm UNE-EN 10020:2001, which substitutes the previous norm UNE-36010, while structural steels are classified according to the European norms EN 10025-2: 2004 and EN-10025-4: 2004.
 

However there are other international norms which are widely used to classify steel such as the American AISI norms (American Iron and Steel Institute) and ASTM (American Society for Testing and Materials) and the German DIN norms or ISO 3506.

The Mikalor catalogue contains a chart which uses both the DIN and AISI norms to describe what materials are used in the manufacture of our range of hose clamps and clips.
