Marine steel refers to the steel used to manufacture the hull structure of sea-going ships and inland ships, usually high-quality carbon steel and high-quality low-alloy steel. Marine steel is required to have certain strength, toughness and hardness, certain low temperature resistance and corrosion resistance, and requires good welding performance.
AH36 steel plate is a steel plate for marine structures. It is a steel plate with a thickness of not more than 150mm used in the manufacture of ocean-going, coastal and inland navigation ships, fishing boats and marine engineering structures. Among them, H stands for high strength and A stands for steel grade, which can be divided into 4 Grade (A, B, D, E), the meaning of this code is high-strength Grade A marine steel with a yield strength of 355Mpa. For steel plates with additional Z-direction requirements, add Z25 and Z35 to the suffix, and their specific uses are structural steel for high-strength ships and marine engineering.
AH36, H stands for high strength A stands for the grade of steel, which can be divided into 4 grades (A, B, D, E). The meaning of this code is high-strength grade A marine steel with a yield strength of 355Mpa.
AH36 steel plate size, shape, weight and allowable deviation:
The size, shape, weight and allowable deviation of the steel plate shall comply with the regulations of GAH36/T709, and the deviation under thickness shall be -0.3mm.
AH36 steel plate delivery status:
AH36 steel plates are usually delivered in hot-rolled, controlled-rolled, normalized, and thermo-mechanical rolled states.
AH36 steel plates shall be delivered in shear or flame cutting.
chemical composition:
C: 0.15-0.18
Si: 0.15-0.50
Mn: 1.20-1.45
P: ≤0.025
S:≤0.015
Nb: 0.015-0.025
Carbon equivalent analysis of AH36 steel plate:
Thickness<=50:<=0.38
Thickness 50-100: <=0.40
Thickness 100-150: <=0.42
Nondestructive testing of AH36 steel plate:
The Z-direction steel plate shall be subjected to ultrasonic flaw detection, and the flaw detection level shall be indicated in the contract.
According to the requirements of the buyer, other steel plates can also be subjected to non-destructive testing by agreement between the supplier and the buyer.
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.
