ASTM A131 grade A marine steel plate is common strength steel plate for hull constructions. ASTM A131 grade A marine steel plate own the minimum yield strength at 235 Mpa and need to do low temperature impacting test at room temperature. ASTM A131 grade A marine steel plate supplied by BBN steel can get the approval from 10 international classification societies: ABS, LR, GL, CCS, NK, DNV, BV, RINA, KR, RMRS.
ASTM A131 grade A marine steel plate chemical composition:
| C | Si | Mn | P | S |
| 0.21 | 0.50 | 2.5×C | 0.035 | 0.035 |
ASTM A131 grade A marine steel plate mechnical property:
| Yield strength (≥Mpa) | Tensile strength (Mpa) | Elongation in ≥, % | |
| 235 | 400-520 | 200mm | 50mm |
| 21 | 24 | ||
ASTM A131 grade A marine steel plate is usually in As rolled, TMCP or Normalized conditions. The maximum rolling thickness of ASTM A131 grade A marine steel plate reaches to 300mm based on guaranteed steel properity.
For the wide heavy ASTM A131 grade A marine steel plate, BBN steel would suggest clients to choose Z-test when rolling, as it can improve the steel plate properity in thickness direction. There are three class for choosing, and they are Z15, Z25 and Z35.
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.
