Combining values from the two systems may result in nonconformance with the standard.  
1.4.1 This specification is expressed in both inch-pound units and in SI units (within the text, the SI units are shown in brackets); however, unless the purchase order or contract specifies the applicable M specification designation (SI units), the inch-pound units shall apply.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Overview

ASTM A1025/A1025M-10(2020), Standard Specification for Ferroalloys and Other Alloying Materials, General Requirements, establishes a set of common requirements for a wide range of ferroalloys and other alloying materials used in steel manufacturing and related industries. Developed by ASTM International, this standard ensures consistent product quality, clear supplier-purchaser expectations, and traceability for chemical composition, size, packaging, and identification.

These general requirements serve as a baseline for several specific ASTM ferroalloy standards. They address key considerations such as order information, chemical analysis, sampling methods, acceptance criteria, certification, and marking. When supplementary requirements or additional testing is needed, this standard provides a framework for incorporating such specifications.

Key Topics

• Applicability: This standard applies to ferroalloys and alloying materials covered by numerous ASTM specifications, including ferromanganese, ferrosilicon, ferrochromium, ferrovanadium, ferromolybdenum, chromium metal, silicomanganese, ferrotitanium, ferrocolumbium, and silicon metal, among others.
• Units of Measurement: Requirements may be stated in either SI (metric) or inch-pound units; only one system may be used per order.
• Ordering Information: Purchasers must specify details such as ASTM designation, grade, size, quantity, packaging, and any supplementary requirements to ensure proper fulfillment.
• Chemical Analysis: The chemical analysis method is determined by agreement between supplier and purchaser. Certification of chemical composition is required for each shipment.
• Sampling and Testing: Sampling for chemical composition follows standard ASTM procedures, with referee methods specified for dispute resolution.
• Screened Product Sizing: Standard size tolerances for lump and crushed products are outlined, along with friability ratings to describe the tendency of materials to break or produce fines during handling.
• Inspection and Certification: The manufacturer must allow reasonable access for inspection and must provide certification that materials have been manufactured and tested in accordance with relevant specifications.
• Packaging and Marking: Clear identification of material, size, lot, and ASTM designation must be provided on shipments and containers.

Applications

ASTM A1025/A1025M-10(2020) supports procurement and production processes in industries that depend on consistent, high-quality ferroalloys and alloying materials, including:

• Steel production: Ensures reliable delivery and quality of alloying agents necessary for meeting steel composition requirements.
• Quality assurance and control: Provides repeatable methods for inspecting, sampling, and testing materials, supporting traceability and conformance to customer or regulatory requirements.
• Supply chain consistency: Facilitates clear agreements and documentation between suppliers and purchasers, minimizing disputes and ensuring reliable product performance.

By following this standard, organizations reduce risk, ensure compliance, and consistently produce or receive materials that meet stringent metallurgical and operational standards.
