General intensity hull structural steel
The general intensity hull structural steel is divided into A,B,C,D four levels,all of their yield strength is no less than 235 MPa and their tensile strength is 400-520 Mpa,but their impact energy is different which is under the differ temperature. The high intensity hull structural steel divides its intensity level is according to the minimum yield strength, and every intensity level is divided into A,D,E,F levels which is based on the different impact toughness. A32,D32,E32,F32 steel grade,their yield strength is no less than 315 MPa,tensile strength is 440-570MPa.And the A,D,E,F stands for their impact toughness under the temperature of 0°C,-20°C,-40°C and -60°C. The yield strength of A36,D36,E36,F36 shipbuilding steel is no less than 355MPa,and the tensile strength is 490-620MPa.And the A,D,E,F stands for their impact toughness under the temperature of 0°C,-20°C,-40°C and -60°C. The yield strength of A40,D40,E40,F40 shipbuilding steel is no less than 390MPa,and the tensile strength is 510-660MPa.And the A,D,E,F stands for their impact toughness under the temperature of 0°C,-20°C,-40°C and -60°C. In addition,there are steel for welding structure with high strength steel quenching tempering:A420��D420��E420��F420��A460��D460��E460��F460��A500��D500��E500��F500��A550��D550��E550��F550��A620��D620��E620��F620��A690��D690��E690��F690�� Steel for Boilers and Pressure Vessels:360A��360B��410A��410B��460A��460B��490A��490B��1Cr0.5Mo��2.25Cr1Mo Z steel:This kind of steel is a level structural steel (called mother grade steel), and on the basis of special treatment (such as calcium treatment, the vacuum takes off gas, argon mixing, etc) and some other proper heat treatments. Steel for shipbuilding Steel for shipbuilding is the general steel for hull structural.It refers to the classification society according to the standard requirements to produce the steel which is used in the manufacturing of the hull structure. This kind of products are often as a special steel orders, production scheduling, sales,generally including a ship aboard, sections, etc. At present,our several big steel factories can manufacture the different national regulation shipbuilding steel,like CCS,ABS,GL,BV,DNV,KDK,LR and so on.
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.
The steel for shipbuilding and oil platform---FH40, is the high tensile strength steel.The shipbuilding steel FH40 is the Hull structural steel.We can provide FH40 shipbuilding steel plate price.
