In larger quantities, it aids the resistance to scaling up to 500 F in air and decreases magnetic hysteresis loss. It affects longitudinal properties to a lesser degree. Existing primarily in the form of manganese sulfide stringers, sulfur is typically added to improve machinability. Titanium, as titanium nitride, also provides grain size control at elevated temperatures in microalloy steels. In excess, titanium is detrimental to machinability and internal cleanness.
Te is added to steel to modify sulfide type inclusion size, morphology and distribution.
The resulting sulfide type inclusions are finer and remain ellipsoidal in shape following hot working, thereby improving transverse properties. A solid semifinished round or square that has been hot worked usually smaller than a bloom. Also a general term for wrought starting stock for forgings or extrusions. A semifinished hot rolled rectangular product. The width of the bloom is no more than twice the thickness and the cross-sectional area is usually not less that 36 square inches.
