LR Grade B Steel Plate for shipbuilding
LR Grade B shipbuilding steel plate is common strength shipbuilding plate which is mainly used for built hull of vessels, ship body construction. Normally when rolling, Air rolled and Control Rolled is ok for ship plate LR Grade B with the thickness equal and below 40 Millimeters, and for thickness above 40mm,the heat treatment shall be Normalized or TMCP, these two technical treatment would improve steel strength in yield and tensile points. Low temperature impacting test for LR Grade B shall be done under zero centigrade when rolling.

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.
