  Details:
 ABS AQ70 and ABS A70 marine steel plates are high-grade materials specifically designed for use in the construction of ships and other marine vessels. These steel grades offer exceptional strength, durability, and corrosion resistance, making them ideal for withstanding the rigorous conditions encountered at sea. In this article, we delve into the chemical composition, mechanical properties, heat treatment, size range, impact testing, and primary applications of ABS AQ70/ABS A70 steel plates, highlighting supply cases by TJC Steel.

Chemical Composition

The chemical composition of ABS AQ70 and ABS A70 steel plates is carefully balanced to achieve the desired mechanical properties. These grades primarily consist of iron, with controlled additions of carbon, silicon, manganese, phosphorus, sulfur, chromium, nickel, molybdenum, and copper. The precise percentages of these elements ensure optimal weldability, toughness, and corrosion resistance.

Mechanical Properties

ABS AQ70 and ABS A70 steel plates exhibit impressive mechanical properties. They possess high yield and tensile strengths, enabling them to withstand significant loads and pressures. Additionally, these grades have excellent impact toughness, resisting cracking or fracturing under low-temperature conditions. The combination of these properties makes ABS AQ70/ABS A70 steel plates suitable for use in critical structural components of ships and marine structures.

Heat Treatment

The heat treatment of ABS AQ70/ABS A70 steel plates is crucial to ensure their optimal performance. Typically, these plates undergo quenching and tempering processes to achieve the desired microstructure and mechanical properties. Quenching rapidly cools the steel, locking in its high-strength phase, while tempering relieves internal stresses and improves toughness. The resulting heat-treated plates exhibit a uniform and stable microstructure, ensuring consistent performance over time.

Size Range

ABS AQ70 and ABS A70 steel plates are available in a wide range of thicknesses, widths, and lengths to meet various application requirements. The specific size range offered depends on the manufacturer and can vary according to customer specifications. However, these grades are typically available in thicknesses ranging from several millimeters to several hundred millimeters, with corresponding widths and lengths suitable for shipbuilding and marine engineering applications.

Impact Testing

Impact testing is a crucial aspect of quality control for ABS AQ70/ABS A70 steel plates. This testing involves subjecting samples of the steel to rapid, high-energy impacts to assess their resistance to cracking or fracturing. The results of impact testing provide valuable insights into the material's toughness and its ability to perform under extreme conditions. ABS AQ70 and ABS A70 steel plates typically meet strict impact requirements specified by classification societies such as the American Bureau of Shipping (ABS), ensuring their suitability for marine applications.

Primary Applications

ABS AQ70 and ABS A70 steel plates are widely used in the shipbuilding and marine engineering industries. Their high strength and corrosion resistance make them ideal for use in hull structures, decks, bulkheads, and other critical structural components. These steel grades are also commonly employed in the construction of offshore platforms, oil and gas pipelines, and other marine infrastructure projects.
