CP800 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 strength and formability of BR400/590TR is much more excellent than normal high strength steel ,Thanks to the combination of high strength and good formability ,the BR450/780TR is a preferred material for automobile industry.
