ABS DQ47 and ABS D47 are high-strength marine steel plates specifically designed for use in the construction of ships and marine vessels. These grades of steel are widely recognized for their excellent mechanical properties and chemical composition, making them suitable for various marine applications.

Chemical Composition

The chemical composition of ABS DQ47 and ABS D47 steel plates is carefully controlled to ensure optimal performance. These grades primarily consist of carbon, silicon, manganese, phosphorus, sulfur, chromium, nickel, molybdenum, copper, and aluminum. The precise balance of these elements ensures high strength, good weldability, and corrosion resistance.

Mechanical Properties

ABS DQ47 and ABS D47 steel plates exhibit remarkable mechanical properties. They possess high yield and tensile strengths, enabling them to withstand the rigorous demands of marine environments. Additionally, these grades have excellent impact toughness, which is crucial for ships and vessels operating in cold climates.

Heat Treatment

The heat treatment process of ABS DQ47 and ABS D47 steel plates is crucial to achieve the desired mechanical properties. These plates are typically quenched and tempered to obtain the required strength and toughness. This process involves heating the steel to a high temperature, followed by rapid cooling (quenching) and then reheating to a lower temperature for tempering.

Dimensional Range

ABS DQ47 and ABS D47 steel plates are available in a range of thicknesses, widths, and lengths to meet various shipbuilding requirements. The thickness of these plates can vary from several millimeters to hundreds of millimeters, depending on the specific application. The plates are also available in various lengths and widths to fit different structural components of ships and vessels.

Impact Testing

Impact testing is a crucial aspect of quality control for ABS DQ47 and ABS D47 steel plates. This testing involves subjecting the steel to sudden and intense loads to assess its ability to resist cracking or fracturing. The results of these tests ensure that the steel plates meet the strict safety standards required for marine applications.

Primary Application Scenarios

ABS DQ47 and ABS D47 steel plates are widely used in the construction of various marine vessels, including cargo ships, tankers, cruise ships, and offshore structures. Their high strength and corrosion resistance make them suitable for hull construction, deck plating, and other structural components that require excellent performance in harsh marine environments.
