Inclusions are present in any steel to a greater or lesser extent according to the mixture and conditions of production. Usually the amount of non-metallic inclusions in steel is not higher than 0.1%. However, the number of inclusions in metal is very high because of their extremely small size. Non-metallic inclusions in steel are foreign ...
Deoxidization is a method used in metallurgy to remove the rest of oxygen content from previously reduced iron ore during steel manufacturing. In contrast, antioxidants are used for stabilization, such as in the storage of food. Deoxidation is important in the steelmaking process as oxygen is often detrimental to the quality of steel produced ...
In C-Mn steel weld metals, it is reported that nucleation of various ferrite morphologies is aided by non-metallic inclusion; in particular oxygen-rich inclusions of a certain type and size are associated with the intragranular nucleation of acicular ferrite.
Note that decrease in carbon content increases the problems with non-metallic inclusions. [7] [needs update] Continuous casting and strip-casting technologies have largely superseded ingot casting techniques in recent times. Through these methods, all steel is killed and the resulting yields are close to 96%.

WEC initiation at MnS inclusions in steel [1] White etching cracks (WEC), or white structure flaking or brittle flaking, is a type of rolling contact fatigue (RCF) damage that can occur in bearing steels under certain conditions, such as hydrogen embrittlement, high stress, inadequate lubrication, and high temperature. WEC is characterised by ...
Sonic Drive-In. Sonic uses the word “cheese” on its menu liberally for items including burgers, chili dogs, tots, and fries, but most of it is more cheese-adjacent, if you will.
