Standard Specification for Aluminum for Use in Iron and Steel Manufacture

ABSTRACT
This specification covers the standard for ingot, bar, rod, cone, nugget or shot aluminum and aluminum alloys proposed for use in manufacturing iron and steel. Each sample shall conform to the chemical composition limits enlisted herein. Test samples can be taken at the time the ingots, bars, rods, cones, nuggets or shots are produced or from the finished product.
SCOPE
1.1 This specification covers aluminum-alloy deoxidizing products of all compositions in the form of ingots, bars, rods, cones, nuggets, shot, or stars, for use in the manufacture of iron and steel. Six of the most commonly used deoxidizing product compositions are designated as shown in Table 1. (A) Analysis shall be made only for copper, zinc, magnesium, silicon, and iron unless the determination of additional elements is required by the contract or order, or the presence of other elements in substantial concentration is indicated during the course of the analysis. In the latter case, the amount of these other elements shall be determined, reported, and the total of copper, zinc, magnesium, silicon, iron, and “other elements” shall not exceed the specified amount prescribed in the last column of the table. Unless otherwise specified in the contract or order, 0.2 % or more of any “other element” shall constitute a “substantial concentration” and require that element to be reported.(B) The following applies to all specified limits in this table: For purposes of determining conformance to these limits, an observed value or a calculated value obtained from analysis shall be rounded to the nearest unit in the last right-hand place of figures used in expressing the specified limit in accordance with the rounding-off method of Practice E29.  
1.2 Units—The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.3 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.  
1.4 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 B37-18 is the internationally recognized standard specification for aluminum products used in the manufacture of iron and steel. Developed by ASTM International, this standard specifies the requirements for aluminum-alloy deoxidizing products supplied in various forms-including ingot, bar, rod, cone, nugget, shot, and star. Used primarily as a deoxidizer in steel and ironmaking processes, these aluminum products play a crucial role in enhancing material quality and final product performance.

ASTM B37-18 sets forth criteria for chemical composition, quality assurance, marking, packaging, and sampling. This specification is vital for steelmakers, materials suppliers, and anyone involved in the procurement, processing, or verification of deoxidizing aluminum and aluminum alloys for iron and steel production.

Key Topics

Aluminum Forms and Compositions

  • Covers aluminum and aluminum-alloy products in multiple shapes: ingots, bars, rods, cones, nuggets, shot, and stars.
  • Specifies six commonly used grades based on chemical composition limits for elements such as copper, zinc, magnesium, silicon, and iron.
  • Outlines impurity limits and stipulates analysis and reporting requirements for additional elements if present in substantial concentration.

Chemical Composition and Analysis

  • Average analysis for each lot must conform to prescribed limits.
  • Sampling during production follows strict guidelines for both batch and continuous processes.
  • Analytical methods include spark atomic emission spectrometry and other recognized test procedures.
  • Methods of determining conformance to specified limits reference ASTM Practice E29 for significant digits and rounding.

Quality Assurance and Inspection

  • Producers are responsible for compliance with all testing and inspection requirements unless otherwise specified.
  • Defines "lot" for sampling purposes and details appropriate procedures for verifying compliance.
  • Purchasers may inspect products at the manufacturer’s facility and have rights for arbitration in case of dissatisfaction.

Marking, Packaging, and Shipping

  • Requires clear identification marking of each casting or shipment.
  • Packaging standards ensure protection from damage and facilitate handling and transportation.
  • Special requirements or marking for government and specific contractual needs are accommodated.

Applications

ASTM B37-18 is widely used in sectors where aluminum deoxidizers are essential for quality iron and steel manufacturing:

  • Steelmaking: Aluminum deoxidizing products are added during steel production to remove oxygen and prevent defects such as porosity.
  • Iron manufacture: Similar application as in steel, enhancing cleanliness and overall material properties.
  • Supply chain: Aluminum producers, metallurgical suppliers, and quality control laboratories use this standard as a benchmark for product specification, quality assurance, and validation.
  • Procurement: Enables accurate ordering, certification, and acceptance of deoxidizing aluminum materials by specifying grade, form, and necessary documentation.

Compliance with this standard helps to ensure the performance, traceability, and consistency of aluminum deoxidizers, meeting both regulatory and industry demands.

Related Standards

Organizations and professionals applying ASTM B37-18 may also reference several related standards, including:

  • ASTM B660: Practices for Packaging/Packing of Aluminum and Magnesium Products
  • ASTM B666/B666M: Practice for Identification Marking of Aluminum and Magnesium Products
  • ASTM B881: Terminology Relating to Aluminum- and Magnesium-Alloy Products
