Geier Date: 20.05.2014Non-Metallic Inclusions - an overview | ScienceDirect TopicsNowadays unlike till the mid-1970s, oxides are dominant inclusions in the weld metal because the S-contents are now very low, usually well below 0.010 %. Also, some sulphur becomes dissolved within oxide inclusions when they are still molten (37 38). Therefore, weld metal oxygen content will be used as the main reference criterion in this comparison.Case-hardening steel Carbodur - DEW-STAHL.COMcase-hardening depth of case-hardening steel at equal carbon curves in the surface layer. According to the diagram, the diffe-rent alloy contents lead to a case-hardening depth that is twice as high in the 17Cr3 steel (CD 0.80 mm) compared with the 17CrNi6-6 steel (CD 1.56 mm) despite the otherwise identical conditions.
