AH36 and EH36 steel plates are high strength marine steel that are widely used in the shipbuilding industry both in hull construction and in the superstructure itself. Both AH36 and EH36 steel plates are applied in the cabin structures of cruisers and ships, construction structural parts of the ships, barges, marine equipment, etc. What is the difference between AH36 and EH36 steel plates?
Chemical composition difference between AH36 and EH36 steel plate:
| Grade | C max | Si max | Mn | P max | S max | Als min | Ti max | Cu max | Cr max | Ni max | Mo max | Nb | V | N max |
| AH36 | 0.18 | 0.5 | 0.90-1.60 | 0.035 | 0.035 | 0.015 | 0.02 | 0.35 | 0.2 | 0.4 | 0.08 | 0.02-0.05 | 0.05-0.10 | |

AH36 and EH36 steel plates have similiar chemical composition and strength. The difference between AH36 and EH36 steel plates mainly lie in the impact temperature. The impact temperature of EH36 steel plates is much lower than that of AH36 steel plates. For more difference between AH36 and EH36 steel plates, welcome to contact us and consult freely.
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.
