Sažetak:
Article deals with the mechanical, fatigue and brittle fracture properties of steel sheets of mark S 700 MC with minimum yield stress of 700 MPa. The chemical composition and technogical regime of rolling process were changed during development of studies steel. The experimental programme was realized at 7 randomly selected meltages (26 coiled sheets) of hot rolled steel sheets with the thickness of 8 and 10 mm. Tensile test showed that 14% of steel sheets had the lower yield stress level like was prescribed (Rm about 21 %) whereas the lower values were measured in longitudinal direction (Re about 9, 9%). Deformation properties in the rolling direction were higher about 38%. The scatter of mechanical properties is not affected by the thickness of steel sheets. The anisotropy of mechanical properties given by the ratio ReL / ReT is in the range from 0, 91 up to 1, 05, RmL / RmT in the range 0, 93 to 0, 97 and A5L / A5T from 1, 0 to 1, 38. Brittle fracture properties of studied steel is guaranteed at 0 °C by notch toughness KCU = 60 J• cm– 2. When U-notch was used, all studied steel sheets successfully passed notch toughness test al – 20 °C for guaranteed level 35 J• cm– 2.
