The ASTM/ASME SA516 NV B cargo ship steel specification covers carbon steel plates, which are mainly used for welding pressure vessels, where improving notch toughness is very important. The NV B cargo ship steel tensile strength range is 55-90MPa, and its versatility makes this specification very popular in applications.
The yield strength of Q690D steel plate is 690 Mpa and the impact temperature is - 20℃. NV B cargo ship steel, Q690D steel plate has high strength, good plasticity and toughness, good weldability and good cold and hot performance. Q690D steel plate is mainly used to manufacture various large engineering structural components and construction machinery. Because of its high strength and good toughness, Q690D steel plate can reduce the self weight of components and meet the requirements of large-scale and lightweight engineering components and equipment under the condition of ensuring strength, stiffness and reliability.
There is an inherent difference between the cold forming properties of low-alloy high-strength steel and carbon structural steel. First of all, a certain amount of permanent deformation of low-alloy high-strength steel requires greater force than NV B cargo ship steel, carbon structural steel of the same size. Second, when low-alloy high-strength steel is formed, a slightly larger allowable amount for springback should be given. According to experience, unless the low-alloy high-strength steel is processed to control the shape of inclusions, it is necessary to use a larger bending radius than carbon structural steel during cold forming.
