Shipbuilding steel plate

2024-05-31

INTRODUCTION:

The strength levels of structural steel for hulls are classified into general strength structural steel and high strength structural steel according to their minimum yield point. Ship plates refer to hot-rolled steel plates used to manufacture hull structures produced in accordance with the construction specifications of classification societies.
