What is ABS AH32 Shipbuilding Steel Plate?

As a hot-rolled high tensile strength steel, AH32 is designed to resist the harsh saline conditions of marine environments, and micro-alloying technology is employed to enhance toughness and resistance to corrosion. As one of the highest performance steels produced in the world, the H series of shipbuilding steels is designed to excel in many mechanical properties.

Grade A steel is the impact force subjected to normal temperature (20 ° C).

Grade B steel impact force at 0 °C.

Grade D steel impact force at -20 °C.

Grade E steel impact force at -40 °C.
