Abstract [en]


This report covers a study concerning the methods that are available for determining the cleanness level for steels. No outstanding method is available for rating clean steels, when clean steel is defined as free of fatigue initiating inclusions. Fatigue strength is to a large extent dependant of the biggest inclusion size in the stressed volume. Examples of methods that can be used for finding and testing material for the presence of big inclusions is reported.
