4 Basic parameters and dimensions

4.1 plate Thickness, maximum deviations depending on the thickness and width of the plate should correspond to the values given in table 1.

Theoretical weight of 1 m of the slab is given in Appendix A and calculated based on nominal sizes based on maximum variance with a density of 2.85 kg/DMГОСТ Р 56370-2015 Плиты из алюминиевых сплавов для судостроения. Технические условия, which corresponds to the density of the aluminum alloy V95 brand. Conversion factors to calculate the theoretical mass of 1 m plate of aluminium alloys is given in Appendix B.

4.2 Plate, depending on the state of the material manufactures with the dimensions given in table 2.

2 Plates of alloy grade 1561Н (АМг61Н) is subjected to a stabilizing vacation at a temperature of 230 °C — 250 °C.

3 elongation at the natural aging of the plates of alloy grade 1985ч for more than 8 days after-school is not regulated.

5.9 On the edges of the plates are allowed flaws and other defects due to the method of production, within the permissible limit deviations on width. In the manufacture of slabs without trimming on edges and ends, beyond the nominal dimensions of the plates, allowed dents, nicks, cracks and other defects due to the method of production.

— when free laying the plate on the reference plane flatness shall not exceed the requirements specified in table 5;

— flatness of the plates of alloy grade 1985ч 1 m of the length in loose packing of plates each side on the plane of the control plate must not exceed 15 mm on the long sides and 30 mm on the short:

— flatness of plates of alloys of 1980 (В48−4) and 1941 (K48−2) is not regulated.
