ASTM A131 is a standard specification for structural steel plates, shapes, and bars used in ship construction. It covers various grades of structural steel, such as high-strength low-alloy steel, carbon steel, and alloy steel intended for use in the construction of ships and marine structures. The ASTM A131 specification is broadly categorized into several grades based on the material properties required for specific applications in the marine industry.
Key points about ASTM A131 material:
Grades: ASTM A131 includes different grades classified by strength levels (A, B, D, E, AH32, DH32, EH32, AH36, DH36, EH36, etc.) to meet varying requirements in terms of strength, toughness, weldability, and corrosion resistance.
Applications: Commonly used for the construction of ships, barges, marine equipment, and offshore structures where high-strength materials with good weldability and impact resistance are necessary.
Chemical Composition: The chemical composition and mechanical properties of ASTM A131 steel grades are specified to ensure they meet the required performance standards for marine applications.
Weldability: ASTM A131 steel is known for its excellent weldability, making it suitable for welding processes used in shipbuilding and marine engineering.
Corrosion Resistance: Some grades within the ASTM A131 specification offer enhanced corrosion resistance properties to withstand exposure to harsh marine environments.
Certification: Manufacturers producing materials according to ASTM A131 must adhere to specific guidelines and quality control measures to ensure the products meet the required standards.
Overall, ASTM A131 steel is widely used in the marine industry due to its strength, weldability, and corrosion-resistant properties essential for constructing reliable and durable ships and marine structures.
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.
