Hull structural steel grade DH36 is mainly produced into DH36 steerl plates, DH36 angle bars, DH36 flat bulbs etc. steel products for ship building and repairing, ocean engineering, etc. The steel grade DH36 equivalent materials have similiar chemical composition and mechanical properties with DH36 steel.
DH36 steel chemical composition (heat analysis):
| Element | Max % | Element | Max % |
| C | 0.18 | Ni | 0.40 |
| Mn | 0.90-1.60 | Mo | 0.08 |
| Si | 0.50 | Al | 0.015 min |
| S | 0.035 | Nb | 0.20-0.05 |
| P | 0.035 | V | 0.03-0.10 |
| Cu | 0.35 | Ti | 0.02 |
| Cr | 0.20 | N |
DH36 steel mechanical properties:
| Grade | Yield Strength | Tensile Strength | Elongation | Impact Energy |
| MPa (min) | MPa | % (min) | (KV J) (min) | |
| -20 degree | ||||
| DH36 | 355 | 490-620 | 21 | 34J |
Hull structural steel grade DH36 equivalent has the advantages of high strength, good comprehensive performance, etc.. It can reduce the weight of the hull, improve the carrying capacity and so on, its use is increasing year by year.
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.
