- John
Known for its exceptional strength, formability, and energy absorption properties, 1180DP steel is a top choice for structural and safety-critical components. This article delves into its key features, production processes, and applications.
Keep reading to learn how SteelPro Group ensures consistent quality and customization options to meet diverse project requirements.
What Is 1180DP Steel?
1180DP (dual-phase) steel represents an advanced high-strength steel (AHSS) that combines excellent mechanical performance with ease of manufacturing. Its dual-phase microstructure consists of a ductile ferrite matrix interspersed with hard martensite islands, providing an ideal balance of high strength and formability. With a minimum tensile strength of 1180 MPa, this steel is designed to handle the most demanding applications, including crash zones, structural reinforcements, and components that must endure extreme mechanical stresses.
1180DP Steel Key Characteristics
Unmatched Strength-to-Mass Efficiency
Achieving high strength without excessive weight, 1180DP steel allows engineers to design lighter components while maintaining or improving safety standards.
Impact Resilience
The dual-phase structure enables effective energy dissipation under impact, making it well-suited for safety-critical parts.
Manufacturing Flexibility
Although it is among the higher-strength AHSS grades, 1180DP steel retains adequate formability and can be welded using conventional techniques, simplifying manufacturing processes.

Efficient Production and Expert Services
The production of 1180DP steel coils follows a complete, precision-engineered process.
Starting with hot rolling to establish thickness and shape, the steel undergoes pickling to remove impurities and create a clean surface. Subsequent cold rolling refines its dimensions, while specialized heat treatments form the dual-phase microstructure that delivers superior strength and ductility.
