Nonmetallic inclusions in important steels

Russian Metallurgy (Metally), 2011
The contamination of 30Cr2Ni4MoV rotor steel with exogenous nonmetallic inclusions is studied. Technological measures intended to decrease the level of contamination of the steel with nonmetallic inclusions and to enhance its quality are recommended.

Nonmetallic inclusions in steel U10A wire

Metal Science and Heat Treatment, 1990
1. In wire of high-carbon tool steel U10A intended for manufacturing sewing machine needles nonmetallic inclusions of two types are observed: globular and drawn-out in shape. 2. The inclusions have a complex composition and they are not pure graphite. They contain a high amount of carbon.

Nonmetallic inclusions in high-speed steel

Metal Science and Heat Treatment of Metals, 1962
1. Various nonmetallic inclusions — oxides, brittle and plastic silicates, and globular bodies — may be encountered in high-speed steel. 2. High-speed steel is primarily contaminated by brittle inclusions the amount of which most frequently corresponds to numbers 3–5 of the TsNIIChM scale.

Nature of nonmetallic inclusions in alloy 58N

Metal Science and Heat Treatment, 1973
1. Alloy 58N, serially produced and used for manufacturing precision scales, is highly contaminated with nonmetallic inclusions, most of which are titanium nitrides and aluminum oxides. These inclusions make it difficult to obtain a high-quality mirror surface on scales, due to which the accuracy of precision machine tools decreases.
