The main reason for the unqualified tensile fracture of high strength ABS AH36 steel plate is the serious central segregation and loosening of the slab structure, which results in the delamination of the specimen after the tensile test and the abnormal granular bainite structure in the center.
Reducing segregation-prone alloying elements can improve the central segregation and porosity of ABS AH36 steel plate slab, thus eliminating the granular bainite structure and fracture stratification, and improving the qualified rate of fracture.
Strict control of rolling process can compensate for the decrease of strength caused by the decrease of segregating elements such as Mn, and ensure the mechanical properties of high strength ABS AH36 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.
