That is to say, in titanium series of interstitial steel , the carbon ,nitro-gen and sulfur atoms should be in the form of Ti(C,N) ,TiS and Ti4C2S2. For some reasons , the content of titanium in IF steel of Baosteel is relatively high.

• 钛系列IF钢的C、N、S原子被完全固定为Ti(C,N),过量的钛以钛的硫化物TiS和Ti_4C_2S_2或固溶形式存在。 由于各种原因,宝钢IF钢钛添加量较多,使过剩钛较高。
