ASTM A131 Grade A is a low carbon steel used for shipbuilding applications. Here are some key details about ASTM A131 Grade A steel:
Chemical Composition (Percentage by weight):
Carbon (C): 0.21% max
Manganese (Mn): 2.5% max
Phosphorus (P): 0.035% max
Sulfur (S): 0.035% max
Mechanical Properties:
Tensile Strength: 58,000 - 75,500 psi (400 - 520 MPa)
Yield Strength: 34,000 psi (235 MPa) min
Elongation in 8 in. (200 mm): 23%
Elongation in 2 in. (50 mm): 27%
Other Characteristics:
Grain Refinement: The steel may be grain refined to improve toughness and impact strength.
Weldability: ASTM A131 Grade A steel has good weldability properties, making it suitable for various welding techniques used in shipbuilding.
Applications:
ASTM A131 Grade A steel is commonly used in the construction of ships and marine structures where good weldability and structural integrity are required.
It's important to note that actual properties may vary depending on specific manufacturing processes, heat treatments, and product forms. Compliance with relevant ASTM standards and project specifications is crucial when using ASTM A131 Grade A steel for shipbuilding applications.
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.
