CCS-A is a grade of ship board. Q235-A is one of ordinary carbon structural steel referred to as ordinary plate. The ship plate is a hot-rolled steel plate produced in accordance with the requirements of the classification society construction specifications for the manufacture of ship hull structures. The general-strength structural steel of China Classification Society's standard is divided into four quality grades: A, B, D, and E (ie CCSA, CCSB, CCSC, CCSD); Q of Q235 represents the yield of this material, and the following The 235 refers to the yield value of this material, which is around 235.
There are many kinds of CCS-A, such as A32, A36, A40, A420, A460, A500, etc., and Q235-A is Q235-A.
The chemical composition of each level of Q235: Q235 is divided into four levels: A, B, C, D (GB/T 700-2006)
Q235A grade contains C ≤0.22% Mn ≤1.4% Si ≤0.35% S ≤0.050 P ≤0.045
And there are many CCS-A, the same is CCS-A, but A32 and A36 are different, A32, A36, A40 are different.
A32 Yield point σs(MPa) not less than 315 Tensile strength σb(MPa)440-570 Elongation σ%22 C ≤0.18 Mn≥0.9-1.60 Si≤0.50 S≤0.035 P≤0.035
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.
