API 2H grade 50 steel plate is a carbon manganese steel plate for offshore structures in accordance with American standards. API 2H grade 50 steel plate has good wear resistance and corrosion resistance, so it is mostly used for making offshore platforms, hulls and other engineering projects. CCS / DNV / ABS / GL / LR / BV / RINA / NK / KR classification society certification is available according to customer requirements.
API 2H grade 50 carbon manganese steel plate chemical composition:
Sulfur S: ≤ 0.035, Phosphorus P: ≤ 0.035, Cr: 0.80-1.10, Ni: ≤ 0.030, Cu: ≤ 0.030, Mo: ≤ 0.015, Titanium Ti: ≤ 0.020.
Mechanical properties of API 2H grade 50 carbon manganese steel plate:
API 2H grade 50 tensile strength σb (MPA): ≥ 785
API 2H grade 50 yield strength σs (MPA): ≥ 590
API 2H grade 50 elongation δ5 (%): ≥ 12
API2HGr50 reduction of area ψ (%): ≥ 50
API2HGr50 impact energy Akv (J): ≥ 47
API 2H gr 50 impact toughness value αkV (J / cm2): ≥ 59
API 2H grade 50 steel is usually delivered as hot rolled or hot forged. If required by the demander (and indicated in the contract), it can also be delivered in the state of heat treatment (annealing, normalizing or high temperature tempering).
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.
