Steel physical, mechanical and usage characteristics are influenced by its elaboration,
secondary treatment, casting and further treatment. But if elaboration and secondary …

The oxygen is an element which has adversely affect to the steel quality because it causes
embrittlement at high temperature, evidenced by the increased susceptibility on overheating …

Steel purity, respectively its high quality, starts as early as its elaboration stage where,
besides an appropriate charge, the process itself has to be carried out accordingly. This …

The existence of gases in the solid metals (hydrogen and nitrogen) assumes the presence of
these gases in metals even before solidification, respectively in the elaboration, secondary …

The quality of finite steel products depends on steel content of hydrogen. On steel
elaboration, in order to remove the dissolved hydrogen, at least one ladle secondary …
