尺寸、形狀、質(zhì)量的允許偏差 鋼板的尺寸、形狀、質(zhì)量的允許偏差應(yīng)符合EN10029的規(guī)定,厚度偏差應(yīng)符合B級(jí)規(guī)定,不平度符合N級(jí)規(guī)定。
Improved deformation properties perpendicular to the surface
For plate thicknesses≥15 mm, the fulillment of one of the three quality classes Z15, Z25 or Z35 in accordance with
EN 10164 or similar rules can be stipulated on the order. These quality classes correspond to a minimum reduction of
area on through-thickness tensile test specimens of 15, respectively 25, respectively 35 % (minimum value for the
average of 3 tests).
