SuperHot-G高成形性高碳熱軋鋼板日本JFE鋼鐵公司特鋼
JFE produces high quality hot rolled special steel SUPERHOT, which is characterized by excellent thickness accuracy, surface quality, and workability in comparison with conventional hot rolled special steels, by applying an advanced hot rolling mill, proprietary technologies, and strict controls. SUPERHOT is widely used in items which cannot be substituted with cold rolled products, such as chain plates, seat belt tongues, recliner gears, and pole parking.
Characteristics
- Excellent accuracy of thickness
Longitudinal thickness deviation is extremely small and the crown is also fl at. Actual measured data of thickness deviation and profi le is shown. - Excellent quality thick sheet
Descaling at the coil form of the strip more than 9mm is possible. - Excellent surface quality
Red scale is controlled in minimum. The example is shown below. - Excellent workability
It is suitable to fi ne blanking, tough standing and slight curvature bending.
Standard
Excellent thickness accuracy product and excellent surface quality products are applicable to all standards.
Excellent quality thick sheet and excellent workability products are mainly applicable to SC, SCM and SCr.
??? 日本JFE鋼鐵公司開發(fā)出了具有高成形性，含碳量0.35%的高碳熱軋鋼板“SuperHot-G”，具有與冷軋鋼板相媲美的板厚精度，板厚僅為3mm，可將厚度允許偏差控制在±80μm以下。該高碳熱軋鋼板的開發(fā)進(jìn)一步擴(kuò)大了對(duì)復(fù)雜形狀部件實(shí)施沖壓成型的范圍，適于加工齒輪及無(wú)級(jí)變速箱（CVT）的活塞等反復(fù)轉(zhuǎn)動(dòng)或往復(fù)運(yùn)動(dòng)的驅(qū)動(dòng)類部件。
