Translated as calm steel and semi-calm steel, this refers to the different degrees of deoxidation during steel manufacturing; a higher oxygen content may have an adverse effect on the properties of the steel.

Carbon steel can be classified according to the deoxidization method into boiling steel (F), killed steel (Z), semi-killed steel (b), and specially killed steel (TZ). Please refer to previous discussions at http://bbs.hcbbs.com/viewthread.php?tid=443244
