Ultra-fine grain hot rolled sheets were produced in 1450 hot mill at PZH Steel, its composition is the same as Q235. The microstructures of ultra-fine grain steel are ferrite and pearlite. Ferrite grain size is about 4 μm. The tensile strength and yield strength of hot rolled sheets are over 510 MPa and 400 MPa respectively. The anisotropy of ultra-fine grain hot rolled sheet is slight. Inclusions are dispersed in steel, so the steel sheet is of good cold-bending property.
