...Abstract Abstract The surface of a hook did not possess the smooth and shiny zinc bloom surface normally observed on hot galvanized steel parts but was matte and rough. Large cracks were observed in the zinc layer. The hook was made of silicon-killed alloy steel 41Cr4. A silicon content of 0.27...

... what caused them to become ineffective. In some cases stabilizers can bloom to the surface of a plastic part and be removed by ablation, dissolution, or evaporation into the environment ( Ref 13 ). In other cases, the additives may simply have been consumed doing the job for which they were intended...

.... The development of scale during preheating of ingots, slabs, or blooms is almost inevitable due to the required long heating times. Sometimes, descaling operations involving water sprays or preliminary light passes in rolling operations are not totally successful, and scale may get rolled into the metal surface...

... surface. The depth of decarburization depends on the temperature, time at temperature, nature of the furnace atmosphere, reduction of area between the bloom and the finished size, and the type of steel. There are several examples of decarburization; there may be a completely ferritic surface layer (total...
