ABS DQ70/ABS D70 marine steel plates are specialized materials designed for use in the construction of ships and marine structures. These high-strength steel grades possess excellent mechanical properties and chemical composition, making them suitable for various marine applications.

In terms of chemical composition, ABS DQ70/ABS D70 steel plates are formulated with precise alloying elements to ensure optimal performance. The carbon content is carefully controlled to provide the necessary strength without compromising weldability. Other alloying elements, such as manganese, silicon, phosphorus, sulfur, nickel, chromium, molybdenum, copper, niobium, vanadium, titanium, aluminum, boron, nitrogen, and calcium, are added to enhance the steel's mechanical properties and corrosion resistance.

Mechanically, these steel plates exhibit exceptional strength and toughness. The ABS DQ70/ABS D70 grades are designed to meet strict standards for yield strength and tensile strength, ensuring the structural integrity of marine vessels. Additionally, they possess good ductility and impact resistance, allowing them to withstand the rigors of the marine environment.

The heat treatment state of ABS DQ70/ABS D70 steel plates is crucial to their performance. These plates undergo controlled heating and cooling processes to achieve the desired microstructure and mechanical properties. This heat treatment improves the steel's toughness, hardness, and resistance to fatigue and corrosion.

Regarding size range, TJC Steel offers ABS DQ70/ABS D70 marine steel plates in various thicknesses, widths, and lengths to meet the specific requirements of customers. The availability of these plates in a range of sizes ensures that they can be easily integrated into various marine structures.

Impact testing is an essential part of the quality control process for ABS DQ70/ABS D70 steel plates. These tests evaluate the steel's ability to withstand sudden loads or impacts, simulating conditions that may occur in the marine environment. The results of these tests ensure that the steel plates meet the strict safety standards required for marine applications.

The primary application scenarios for ABS DQ70/ABS D70 marine steel plates include the construction of hulls, decks, bulkheads, and other structural components of ships and offshore platforms. Their high strength and corrosion resistance make them ideal for use in both freshwater and saltwater environments.
