... 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...

... Abstract Chain link, a part of a mechanism for transferring hot or cold steel blooms into and out of a reheating furnace, broke after approximately four months of service. The link was cast from 2% Cr austenitic manganese steel and was subjected to repeated heating to temperatures of 455 to 595...

... Abstract A drum pinion shaft (1030 steel) which was part of the hoisting gear of a crane (capacity 18,140-kg) operating in a blooming mill failed while lifting a 9070 kg load. Chatter marks, rough-machining marks, and sharp corner radii were revealed in the keyway which extended into a shoulder...

... original ingot/bloom stage gradually enlarged in rolling/heat treatment. The defect in Fig. 2 with irregular contour and greater width is suggestive of entrapment of slag/oxides inclusion. The widening of the outline might have been caused by oxidation of an initially present fissure which was filled up...

... which are to be fabricated into heavy sections. Also, the tendency for the formation of hydrogen-induced defects is greater with alloy steels than with carbon steels [ 12 ]. During rapid cooling of heavy-sectioned steel casting, e.g., a thick slab or a bloom, there is little diffusion of hydrogen out...

... 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...

... in unacceptable forgings. 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...

..., decarburization is produced when oxygen in the atmosphere at temperature reacts with and removes carbon from the hot 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...
