ASTM A625/A625M-13(2024) PDF

Overview

ASTM A625/A625M-13(2024) is the standard specification for single-reduced black plate tin mill products, developed by ASTM International. This specification covers thin, low carbon, cold-reduced steel supplied in coils and cut sizes. Black plate is a critical base material used in the manufacturing of containers, closures, signage, toys, and an extensive range of products, as well as in plating operations. The standard details product characteristics, surface finishes, supply conditions, and ordering guidelines, supporting efficient procurement and consistent quality for industrial users.

Compliance with ASTM A625/A625M ensures that black plate products meet rigorous international quality and dimensional requirements. The standard is recognized globally and aligns with principles developed by the World Trade Organization's Technical Barriers to Trade (TBT) Committee, supporting international trade and interoperability.

Key Topics

• Product Scope: Covers single-reduced black plate from low carbon, cold-reduced steel, available in both inch-pound (A625) and SI (A625M) units.
• Supply Options: Available in coils or cut-to-length sheets, furnished either oiled or dry and with optional surface treatments.
• Surface Finishes:
  • Ground roll finishes (e.g., lustrous smooth, with or without grit lines)
  • Shot-blasted or textured finishes for specific applications
• Dimensional Standards: Thickness supplied from 135-lb base weight (0.0149 in.) and lighter in A625 or 0.378 mm and lighter in A625M.
• Ordering Information: Specifies product name, surface appearance, finish, thickness, width, length, steel type, mechanical designation, application, quantity, coil and packaging requirements, and special needs.
• Measurement Units: Both inch-pound and SI units are accepted as standard, but cannot be combined in a single order.

Applications

Single-reduced black plate tin mill products are engineered for versatility in a range of industrial, commercial, and consumer environments. Typical practical applications include:

• Packaging and Containers: Used as the base for tinplate and tin-free steel products in food cans, beverage containers, and industrial packaging due to its formability and surface quality.
• Closures and Ends: Suitable for manufacturing lids, caps, and closures that require precise dimensions and high surface integrity.
• Signage and Displays: Provides a durable, printable surface for signs and advertising displays.
• Toys and Consumer Goods: Used for toys, household items, and decorative products, benefiting from clean finishes and reliable mechanical properties.
• Metal Plating: Serves as a base material for subsequent coating or plating processes, supporting corrosion protection and enhanced aesthetics.

Proper transit and storage procedures are necessary to prevent rusting, as single-reduced black plate is susceptible to corrosion if not handled correctly. Supplemental oiling or surface treatments may be specified depending on the application.

Related Standards

For complete and consistent technical requirements, ASTM A625/A625M refers to several associated standards:

• ASTM A623 / A623M: General Requirements for Tin Mill Products, covering mechanical properties, dimensions, tolerances, and other product characteristics.
• Other Tin Mill Product Specifications: For chemically treated, oiled, or specialty surface finishes, refer to specific guidelines in related ASTM standards.
• ISO and International Trade: Developed per WTO TBT principles, enhancing compatibility with global purchasing and regulatory frameworks.

Summary

The ASTM A625/A625M-13(2024) standard is an essential reference for producers, buyers, and end users of single-reduced black plate tin mill products. By standardizing product characteristics and providing clear guidance on ordering and applications, it supports high-quality production and efficient international trade in steel-based packaging, fabrication, and industrial sectors.
