ABS Grade EH32 Shipbuilding Steel Plate - Low Temperature High Strength Marine Steel Plate

1. What is ABS Grade EH32 shipbuilding steel plate?

ABS Grade EH32 steel plate is a high-strength structural steel plate for shipbuilding, certified by the American Bureau of Shipping (ABS), which offers excellent low-temperature impact toughness and is specifically designed for extreme low-temperature marine environments.

Because ABS Grade EH32 shipbuilding steel plate retains excellent impact toughness even in harsh marine environments at -40°C, it is the ideal choice for structural components in polar-class vessels, offshore platforms and icebreakers.

2. Meaning of the Designation

E: Quality grade (Impact toughness grade: exhibits good toughness at -40°C)

H: High-strength steel

32: Minimum yield strength of 315 MPa (≈ 32 kgf/mm²)

Chemical Composition (Heat Analysis, wt %)

Carbon Equivalent (wt %)

Calculation formula (IIW): CEV = C + Mn/6 + (Cr + Mo + V)/5 + (Ni + Cu)/15

Tensile test properties

Impact energy KV2 (Charpy V-notch Impact Test)

The key advantage of ABS Grade EH32 high-strength structural steel plate for shipbuilding, certified by the American Bureau of Shipping (ABS), is its ability to maintain excellent impact toughness even at temperatures as low as -40°C, making it ideal for shipbuilding in cold waters and polar engineering projects.
