ASTM A980/A980M-19

Standard Specification for Steel, Sheet, Carbon, Ultra High Strength Cold Rolled

ABSTRACT
This specification covers the standard for cold rolled ultra high strength carbon steel sheet in coils or cut lengths. The sheet shall be produced from aluminum killed steel and shall undergo continuous annealing to austenitic temperatures and then be water quenched. Cast or heat analysis shall conform to the prescribed chemical composition requirements in carbon, manganese, phosphorus, sulfur, and aluminum. Tension test shall be done on the point immediately adjacent to the material to be tested and properties shall conform to the specified tensile strength. The sheet shall have a matte surface finish texture and shall have cut edges. Unless otherwise specified, the sheet shall undergo oiling.
SCOPE
1.1 This specification covers a cold rolled ultra high strength carbon steel sheet in coils or cut lengths. The product is available in five strength levels. The steel's strength is obtained by water quenching from an austenitic temperature resulting in a martensitic microstructure. This product is intended for miscellaneous applications where ultra high strength, weight saving, and good weldability are important.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Overview

ASTM A980/A980M-19 is the internationally recognized standard specification for cold rolled ultra high strength carbon steel sheet in coils or cut lengths. Published by ASTM International, this standard sets the requirements for the chemical composition, mechanical properties, surface finish, and manufacturing processes of such steel sheet products. ASTM A980/A980M-19 is critical to industries seeking structural components that deliver ultra high strength, weight savings, and reliable weldability.

Key Topics

• Ultra High Strength: The steel sheet covered by this standard is engineered for high performance. It achieves superior tensile strength through water quenching from austenitic temperatures, creating a martensitic microstructure. Five strength grades are available, supporting a range of engineering needs.
• Chemical Composition: Maximum and minimum limits for elements including carbon, manganese, phosphorus, sulfur, and aluminum are defined. The use of aluminum-killed steel ensures consistency and improved properties.
• Mechanical Requirements: Rigorous tensile strength testing is required to ensure compliance with specified mechanical properties, ensuring the material’s fitness for demanding applications.
• Surface and Edges: A matte finish surface texture and cut edges are standard. Sheets are typically supplied oiled unless dry surface is specified by the purchaser.
• Dimensional Versatility: Available in both coils and cut lengths, with procurement options for various dimensions and coil sizes per customer needs.
• International Applicability: The standard supports use of either SI or inch-pound units independently, which accommodates global industry requirements.

Applications

The ASTM A980/A980M-19 standard is widely applied in sectors that demand lightweight structural steel with high mechanical performance and fabrication flexibility. Key applications include:

• Automotive Manufacturing: Used in body-in-white components, reinforcements, or safety-related structures where high strength and reduced weight improve performance and efficiency.
• Transportation Equipment: Ideal for truck bodies, trailers, and railway components.
• Construction and Infrastructure: Applied in high-stress structural members, casings, and security panels, benefiting from the steel's strength and weldability.
• Industrial Machinery and Components: Utilized for machine parts, protective covers, and wherever durability under load is essential.

The high strength-to-weight ratio and reliable weldability make these cold rolled steel sheets especially valuable in innovation-driven and cost-sensitive manufacturing environments.

Related Standards

Users of ASTM A980/A980M-19 should also consider relevant related standards for reference or in procurement processes:

• ASTM A568/A568M: General requirements for carbon, structural, and high-strength low-alloy hot-rolled and cold-rolled steel sheet.
• ASTM Standards for Weldability: Provide guidance on processes and quality for joined ultra high strength steels.
• ISO 4995 / ISO 3573: International norms for cold rolled steel sheet that may be referenced for cross-compliance.
• SAE J2340: Grades for high strength low alloy (HSLA) steel sheets.

ASTM A980/A980M-19 ensures quality and performance in the supply of cold rolled ultra high strength carbon steel sheets, meeting the stringent requirements of today’s advanced structural and safety-critical applications. This standard supports traceable procurement, robust materials verification, and enhanced product reliability for global industries.
