SuperHot-G高成形性高碳热轧钢板日本JFE钢铁公司特钢
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钢铁公司开发出了具有高成形性，含碳量0.35%的高碳热轧钢板“SuperHot-G”，具有与冷轧钢板相媲美的板厚精度，板厚仅为3mm，可将厚度允许偏差控制在±80μm以下。该高碳热轧钢板的开发进一步扩大了对复杂形状部件实施冲压成型的范围，适于加工齿轮及无级变速箱（CVT）的活塞等反复转动或往复运动的驱动类部件。
