DNV GL grade D steel plate and DNV GL grade E ship steel are both common strength steel plate for shipbuilding and ship repairs. Both DNV GL grade D steel plate and DNV GL grade E ship steel own minimum yield strength of 235 Mpa, and tensile strength of 400-520 Mpa.
Difference between DNV GL grade D steel plate and DNV GL grade E ship steel in chemical composition:
Elements | DNV GL grade D | DNV GL grade E |
C | 0.21 | 0.18 |
Mn(≥) | 0.6 | 0.7 |
P | 0.035 | 0.035 |
S | 0.035 | 0.035 |
Si | 0.10-0.35 | 0.10-0.35 |
Difference between DNV GL grade D steel plate and DNV GL grade E ship steel in mechanical properties:
Properties | Strength | DNV GL grade D | DNV GL grade E |
Mechanical Property ≥ | Yield Strength(Mpa) | 235 | 235 |
Tensile Strength(Mpa) | 400-520 | 400-520 | |
Impacting Test Temperature(℃) | -20 | -40 |
The main difference between DNV GL grade D steel plate and DNV GL grade E ship steel is the temperature when doing impacting test. DNV GL grade D steel plate has to be under minus 20 centigree, while DNV GL grade E ship steel should be under minus 40 centigree.
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.
