AB/EQ51 is an American standard high-strength steel plate. There are also AB/EQ43 and AB/EQ47 steel plates under this standard.
Chemical composition of AB/EQ51 steel plate:
| C | Si | Mn | P | S | Ni+Cr+Mo | Nb+V+Ti | Ceq |
| 0.07 | 0.22 | 1.20 | 0.005 | 0.002 | 1.84 | 0.065 | 0.47 |
| 0.14 | 0.34 | 1.55 | 0.010 | 0.003 | 0.76 | 0.093 | 0.49 |
AB/EQ51 steel plate performance standard:
| Grade | Position | RP0.2/mpa | RM/MPa | Elongation A% | -40℃ Longitudinal AKV.J |
| AB/EQ51 | 1/4 | ≥500 | 610-770 | ≥16 | ≥50 |
AB/EQ51 steel smelting method:
Whether it is low-carbon bainite steel or traditional low-alloy steel, in order to make effective and reasonable use of various strengthening mechanisms and achieve a good match between the strength and weldability of the steel plate, the most economical and effective means is to reasonably use controlled rolling controlled cooling process. Make adequate organization and grain preparation for the later quenching and tempering of the steel plate.
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.
