Shipbuilding steel plate grade DH36 is hull structural steel that processes commendable toughness properties, good tensile strength and excellent corrosion resistance and welding properties. Shipbuilding steel plate grade DH36 is mainly used for platform and shipbuilding.
When rolling shipbuilding steel plate grade DH36, TMCP or Normalized shall be done for heat treatment, and low temperature impacting test have to be done under minus 20 centigree for DH36 steel. In order to improve the thickness-direct steel property for shipbuilding steel plate grade DH36, Z-test is necessary, which includes different classes: Z15, Z25 and Z35.
Shipbuilding steel plate grade DH36 is also conducted tests such as positive material identification test, hardness test, intergranular corrosion test, pitting resistance test, mechanical test, chemical test etc. to assure its quality.
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.
