CP800 steel has the following features :
- CP steel is one kind of ultra high strength steel. Its microstructure is mainly made of ferrite and bainite with a small amount of martensite, residual austenite and pearlite.
- The grain size is fine due to the microalloying additions such as Ti , Nb, etc.
- Apart from hard phases such as martensite and bainite, matrix is also strengthened by small dispersed precipitates.
- The chemical composition system is the same as DP and TRIP steels.
- Its yield ratio is relatively high and its elongation is relatively low compared to those of DP steels and TRIP steels in same tensile strength level.
- With good benability and stretch flangeability, CP steel can be used to manufacture parts with complex shapes.)
