OPTIMIZING THE TECHNOLOGY FOR MAKING STEEL 08Yu WITH A CARBON CONTENT BELOW 0.03 percent

摘要

Ferrite and cementite grain growth is seen on some heats of steel 08Yu when it is made by the standard technology in accordance with GOST 9045-93. A study was made of the effect of the chemical composition of the steel and the parameters of the hot- and cold-rolling operations on the microstructure of steel 08Yu. It was found that a low carbon content in the steel is the main factor affecting its microstructure.
