ISO 5454:1980

Overview

ISO 5454:1980 - "Ferrotitanium - Specification and conditions of delivery" defines the requirements for ferrotitanium usually supplied for steelmaking and foundry use. The standard covers product definition, ordering information, delivery methods, chemical composition ranges, grain-size classifications, sampling and analysis principles, and rules for dispatch, packaging and storage. It ensures consistent quality and traceability for ferrotitanium used as a ferroalloy in metallurgical processes.

Key topics and requirements

• Scope and definition: Ferrotitanium is defined as an iron‑titanium alloy with nominal titanium contents in specified ranges (distinct product designations cover low, medium and high titanium grades).
• Delivery methods (lot constitution):
  • Lot by single cast (or part of a continuous cast)
  • Lot by grouped casts of the same grade
  • Lot by mixing and crushing casts to a specified granulometry (typically < 50 mm) and homogenizing
• Cast uniformity: Titanium content of casts (or cast parts) within a delivery must not differ by more than 3 percentage points (absolute) between casts unless otherwise agreed.
• Chemical composition: The standard specifies principal element ranges for several ferrotitanium designations (including variants with aluminium additions). Limits for common impurities (Si, Mn, C, P, S, V, etc.) are given or may be agreed between supplier and purchaser. The standard notes control of tin content where relevant.
• Grain-size classes: Ferrotitanium is supplied as lumps or crushed particles with sieve‑based size classes (e.g., classes covering 3.15–200 mm down to 3.15–10 mm); sieving is specified on square‑aperture steel sieves.
• Sampling and analysis:
  • Sampling and sample preparation referenced to ISO 3713 (and related sieve standards)
  • Supplier normally performs sampling at storage; representative of buyer may be present
  • Supplier provides a certificate of analysis for titanium content and other agreed elements
  • Procedures for discrepant results: bilateral re‑analysis and, if necessary, arbitration
• Packaging, transport and storage: Packed, transported and stored in accordance with applicable international regulations (examples referenced include RID and the IMDG code).

Applications and users

• Primary applications: Steelmaking and foundry use where ferrotitanium is used as a ferroalloy for alloying and process control.
• Typical users:
  • Steel mills and foundries specifying ferrotitanium for melt additions
  • Ferrotitanium producers and distributors preparing deliveries and certificates
  • Quality assurance laboratories and procurement teams verifying compliance
  • Logistics and storage managers handling packaging and transport

Related standards

• ISO 3713 - Sampling and sample preparation for ferroalloys
• ISO 565 - Sieve testing / square‑aperture steel sieves
• ISO 4551 - (referenced for sieving analysis of ferroalloys)
• Note: ISO 5454 anticipates further standardization of chemical analysis methods for ferrotitanium.
