Hull structural GL grade A steel is one of the most common shipbuilding steel materials. Hull structural GL grade A steel is to meet rather strict requirements: strength, flexibility, high manufacturability, weldability, cost, reparability, etc.
Hull structural GL grade A steel properties:
| Mechanical Properties(%) | Chemical Composition(%) | |||||||
| Grade | Yield(MPa) | Tensile Strength | Elongation | C | Mn | Si | S | P |
| GL grade A | 235 | 400-520 | 22 | ≤0.21 | ≥2.5C | ≤0.5 | ≤0.035 | ≤0.035 |
Hull structural GL grade A steel properties differ in high cold-resistance, good welding characteristics and increased fracture strength.
China shipbuilding industry has been making rapid progress due to huge investments in the sector and its competitive price strategy, challenging the dominant positions of South Korea and Japan. Meanwhile, China shipbuilding steel such as Hull structural GL grade A steel also gets rapid development and takes leading position in the International trade.
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.
