In this paper, the bending and bullet-proof properties of steel plate BTP500 are tested. The results of 90° folding test for steel plate BTP500 with thicknesses of 6 mm and 9 mm meet the requirements; the tensile strength of steel plate welded with ferritic welding wire is 100 MPa higher than that of the steel plate welded with austenitic welding wire through comparing the results of performance tests for steel plate BTP500 welded with ferritic welding wire and austenitic welding wire. The impact energy of the test plate welded with ferritic welding wire at -40 ℃ is 20~30 J and the weld test of steel plate BTP500 could meet the agreement requirements. With the penetration of bullet, both of the steel plates BTP500 with thicknesses of 6 mm and 9 mm by industrial trial production are not penetrated, which are with very good bullet-proof and anti-penetration properties as well as the bullet-proof property could meet the agreement requirements.
