Abstract: The low alloying high strength weather-resisting steel SPA-H strip-C≤0. 12,Mn 0.20~0.50,Si0.25~0.75,P0.07~0. 15,S≤0.04,Cu0.25~0.60,Cr0.30~1.25,Ni≤0.65 has been trial-produced by flow sheet of& an 100 t electric arc fumnace-ladle furnace-concaster-rolling mill at Nanjing Steel. The results of examination and service showed that the steel structure was ferrite+pearlite and has higher cleanliness,the yield strength of steel 345~435 MPa,tensile strength 480~570 MPa,elongation 23%~43%,and the steel has excellent weld ability
