Head Lun'ov Valentyn Vasyl'ovych, Registration Date 09-10-2000 Organization Zaporizhzhie State Technical University popup.description2 Experimental tests of 20Г2Л and 40Г2Л steels both with high content (0,04%) and ordinary (0,008%) content of nitrogen were performed. It was found out that nitrogen in metals is in the form of manganese nitrides which have to be further investigated.Mechanical tests proved the increase of strength qualities in metals with high nitrogen concentrations.
