Its popularity is due to its ability to imbue steel with a uniform fine-grained structure, while at the same time avoiding too much softening of the steel.Normalizing rolling - VoestalpineEffects of normalizing rolling. The grain size is minimized through low forming temperatures because grain growth is greatly reduced during recrystallization. The material grain is refined, and the microstructure is homogenized. The material is subsequently cooled. The steel properties are similar to those of normalized-annealed plates.
The phrase "fully killed fine grain practice" doesn't mean that the material has been normalized.

Fine Grain Practice - Metal and Metallurgy engineering is fined grain steel normalizeOct 06, 2005 · 3). No. Normalizing is a heat treatment process and does not equate with fine grain practice. Fine grain practice begins with deliberate alloy additions during steel making. 4). No. Please note, if you intend to use these plates in a pressure vessel, you need to go back to the original code of construction (ASME or other) to re-certify the plates.
The series of normalized rolled fine-grain structural steels is characterized by a minimum yield strength of 275 - 355 MPa, by good weldability and high resistance to brittle fracture.
