The general strength steel for hull structure is divided into four grades: A, B, D and E. The yield strength (not less than 235N/mm^2) of these four grades of steel is the same as the tensile strength (400~ I-520n / mm ^ 2). , kodwa ifuthe lamandla kumaqondo obushushu ahlukeneyo yahlukile;
Isivuno samandla e-A32, i-D32, E32, kwaye i-F32 ingaphantsi kwe-315n / mm ^ 2, kunye namandla amathandathu-45570n / 2. Ubunzima bempembelelo enokufumaneka nge-0 -40 °, -60 °;
Isivuno samandla e-A36, i-D36, E36 kunye ne-F36 ayingaphantsi kwe-350n / mm ^ 2, kunye namandla abunjiweyo yi-490 ~ 6.2 mm ^ 2. Ubunzima bempembelelo enokufumaneka nge-0 -40 °, -60 °;
Isivuno samandla e-A40, i-D40, E30, kwaye i-F40 ayingaphantsi kwe-390n / mm ^ 2, kunye namandla apheleleyo yi-510 ~ 40n / mm ^ 2. Ubunzima bempembelelo enokufezekiswa nge-0 -40 ° no -60 °.
