The selection factors of shipbuilding steel

It has various factors to consider when select shipbuilding steel, including the type of ship, the size of ship, navigation environment, cargo capacity and service life and so on.

The type of ship
Different types of ships have different requirements for the performance of shipbuilding steel. For example, oil tankers use steel with good corrosion resistance to avoid oil leakage and environment pollution; cargo ships use steel with high strength and toughness to carrying a large amount of cargo.

The size of ship
Larger ships require steel with higher strength to withstand greater loads and water pressure.

Navigation environment
Different navigation environments have different corrosion and wear on shipbuilding steel. For example, seawater is more corrosive than freshwater.

Service life
If want a ship to use for many years, it is significant to choice shipbuilding steel with higher corrosion resistance and wear resistance.

Common shipbuilding steel grades
ASTM A131 Grade A, B, D, E
ABS Grade A, B, AH32, DH32, EH32, AH36, DH36, EH36
DNV Grade A, B, D, AH32, DH32, EH32, AH36, DH36, EH36
CCS Grade A, B, AH32, DH32, EH32, AH36, DH36, EH36
