Abstract

Non-metallic inclusions usually deteriorate mechanical properties and surface quality of steel products. Presence of non-metallic inclusions might have negative affected some of the mechanical properties of steels like ductility, toughness, anisotropy, and formability. Macroscopic method for assessing the content of non-metallic inclusions in forged or rolled steel products is used for determination non-metallic inclusions visible to the naked eye or with aid of a magnifying with magnification of not more than 10 times. Only inclusions equal to or greater than 1 mm long are taken into consideration. In this paper is given procedure for blue fracture test method applied on bar diameter  60 mm bearing steel 100Cr6.
