The DNV GL EH32 marine grade steel plate is used in the construction of ships and marine engineering equipment. So DNV GL EH32 marine grade steel plate is required to not only have good strength and toughness matching, low temperature toughness, easy welding and other performance requirements, but also have high ductility. The purpose is to allow the DNV GL EH32 marine grade steel plate to absorb the energy of the collision when the ship and marine engineering equipment collide and run aground, thereby improving the equipment's anti-collision ability and contributing to the realization of safer and more reliable marine transportation.
Through alloy reduction, controlled rolling and controlled cooling processes are used to adjust the microstructure and grain size of the steel plate to obtain DNV GL EH32 marine grade steel plate with high yield, stable strength and toughness, and particularly high ductility. Such DNV GL EH32 marine grade steel plate has the characteristics of high ductility (elongation ≥ 33%), excellent low temperature toughness (-40℃ impact energy ≥200J), and good fracture toughness (ndtt temperature ≤-40℃).
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.
