ASTM A131 is the standard specification for structural steel plates primarily used in ship construction. Steel grades covered in ASTM A131 specification require CVN impact testing and are classified by minimum yield strengths.
ASTM A131 grade DH32 steel plate has good toughness properties, higher strength, strong corrosion-resistance, good processing properties, and good welding properties.
ASTM A131 grade DH32 steel plate chemical composition:
| Grade | C max | Si max | Mn | P max | S max | Als min | Ti max | Cu max | Cr max | Ni max | Mo max |
| A131 grade DH32 | 0.18 | 0.50 | 0.90-1.60 | 0.035 | 0.035 | 0.015 | 0.02 | 0.35 | 0.20 | 0.40 | 0.08 |

ASTM A131 grade DH32 steel plate is used to contribute hull of ships and the cranes of break bulker and vessels in low temperature oceans. ASTM A131 grade DH32 steel plate is approved by ABS, DNV, GL, BV, LR, NK, RINA and other classification societies. What's more, ASTM A131 grade DH32 steel plate can be used in manufacturing the ship's hull structure whose weight is below 10000 tons.
GB T 5312 Carbon and carbon-manganese steel seamless steel tubes and pipes are mainly for ship use, also known as shipbuilding steel pipes. Under GB T 5312, there are mainly 5 steel grades: grade 320, 360, 410, 460 and 490. Each grade covers three levels: I, II, III.
Angle steel, commonly known as angle iron, is a long strip of steel whose sides are perpendicular to each other. There are equal angle steels and unequal angle steels. The two sides of equal angle steel are equal in width. The unequal angle steel is also known as L shape profile steel.
Flat bar steel can be produced according to the user's needs, with fixed thickness, width and length. It can reduce the cutting process for users, reduce the consumption of labor and materials, and also reduce the processing loss of raw materials.
Bulb flat steel for shipbuilding
The bulb flat steel is a kind of medium section material which is mainly used in the field of shipbuilding and bridge building, and the shipbuilding bulb flat steel is an auxiliary medium section material for shipbuilding.
