- a sheet of Cr-Mo-V steel which has been ladle metallurgically treated and vacuum degassed, having a composition in wt% of 0.45 carbon (C), 0.62 silicon (Si), 0.64 manganese (Mn) , 0.016 phosphorus (P), 0.007 sulfur (S), 3.35 chromium (Cr), 1.62 molybdenum (Mo), 0.32 vanadium (V) was rolled from a slab block to a thickness of 7.5 mm. From the sheets samples were made, the same tempered and tested with different technologies. Table 1 shows the tempering parameters and the mechanical values achieved. Sample No. Härtetemp.
- Fig. 1 the percentage of retained shots in dependence on Sheet thickness shown. From a plate thickness of 6 mm upwards is the same energetic conditions of shelling the proportion of shots held from a martensitic and hardening steel according to the invention manufactured sheet practically the same.
- the profitability is to determine that the material of the invention has an alloy content of about 6%, that of the martensitic hardening steel (comparative material) has 41.5% and thus has significantly higher costs.

It should also be noted at this point that a further increase in the property level is achieved by lowering the sulfur content below 0.005% by weight.
- inventively achieved advantageous material properties are increasingly pronounced in a bombardment pronounced when the parts are coated to higher strength values of about 1900 N / mm 2 .
- This is also due to the fact that a narrower range of the concentration of each alloying element interacts favorably with the other constituents of the alloy to favor the conversion and formation of the microstructure of the material in the thermal anneal, thereby improving the onset and tempering performance and so on extensive isotropy with low residual stresses.
- this a strength of greater than 1800 N / mm 2 , preferably greater than 2000 N / mm 2 , in particular of about 2100 N / mm 2 , with a toughness at room temperature greater than SEP 150 J, preferably having greater than 185 J, in particular of about 245 J as measured by (S e teel isen rüfblatt P) in September 1314, are buildable sheets therefrom with the highest breakdown resistance.

- a sheet made of pan-metallurgically treated steel having a composition in wt.% Of 0.52 carbon (C), 0.12 silicon (Si), 0.22 manganese (Mn), 0.014 phosphorus (P), 0.003 sulfur ( S), 1.42 chromium (Cr), 0.11 molybdenum (Mo), 0.09 tungsten (W), 0.004 (As + Sb + Bi + Sn + Zn + B), which was subsequently electroslag remelted with a thickness made of 7.5 mm and tempered to a hardness of 57 HRC, yielded at a hardening temperature of 880 ° C and air cooling after tempering at 200 ° C, a yield strength of the material of Rm 2265 N / mm 2 at a notch impact of average 202 J. In the bombardment test in comparison with tempered carbon steel under otherwise identical conditions, a 68.7% higher number of retained shots was recorded.
- a comparison of inventive Sheets and such from each of the highest values tempered carbon steel and martensite hardening steel using a bombardment test is the Percentage of retained shots as a function of the sheet thickness shown. From a sheet thickness of 5 mm to a thickness of 10 mm proportionally those of martensitaushärtbarem steel and of the Shoots held according to the invention are substantially equal to minor ones Advantages of the material according to the invention in the range over a sheet thickness of 6 mm.
