DP600 STEEL Coils & Sheets – AUTOMOTIVE STEEL
DP600 STEEL Coils & Sheets – AUTOMOTIVE STEEL
DP600 steel is a high-strength, low-alloy dual-phase steel, with “DP” indicating its dual-phase microstructure and “600” its tensile strength of 600 MPa. Comprising 98% iron and small amounts of carbon, manganese, and silicon, it offers an excellent balance of strength and ductility. Available in sheets or coils, DP600 is extensively used in the automotive industry for structural components, body panels, crash components, and safety parts.
SteelPro Group provides DP600 steel products in compliance with SAE J2340, ISO 20805, and EN 10346 standards. Our DP600 steel is available in multiple forms, including cold-rolled coils, sheets, hot-dip galvanized coils, pipes, and precision-formed components.
Description
What is DP 600?
DP600 steel, primarily composed of approximately 98% iron with additional small amounts of carbon (0.15%), manganese (1.5%), and silicon (0.5%), is a dual-phase steel. It comes in solid sheets or coils with a metallic grey color. Known for its high strength and ductility, this advanced high-strength steel (AHSS) is ideal for automotive structural and safety components. Typically processed through hot rolling, DP600 belongs to the category of dual-phase steels.Characteristics of DP 600 Steel

DP600 Heat Treating Instructions
DP600 undergoes a precise heat treatment process to enhance its mechanical properties, including improved strength, ductility, and formability. The specific heat treatment parameters are carefully controlled to achieve the desired balance of hardness and toughness, making it suitable for various demanding applications.
DP600 Surface Finish
DP600 can be finished with a variety of surface treatments to enhance its performance and appearance, depending on the intended use. These treatments may include coating, galvanizing, or polishing to improve corrosion resistance, wear resistance, and overall durability. Surface roughness and texture can also be adjusted to meet specific functional or aesthetic requirements. Grades can be customized according to specific requirements.
Customized grades are available upon request.
