Overview

ISO 5453:1980 - Ferroniobium (ferro-niobium) - Specification and conditions of delivery - defines the standard requirements for ferroniobium typically supplied for steelmaking and foundry use. The standard covers product definition, ordering information, permitted chemical composition ranges, methods for constituting deliveries, sampling and testing, certification, and rules for packaging, dispatch and storage.

Key Topics

• Product definition
  • Ferroniobium is an iron–niobium alloy. The standard specifies principal grades by niobium content (commonly 55.0% to 70.0% Nb by mass; e.g., FeNb65 nominally 60–70% Nb).
• Ordering information
  • Orders should specify quantity, method of delivery constitution, chemical designation, particle-size classes, and requirements for certificates and packaging.
• Methods of delivery
  • Deliveries may be by single cast/heat, grouped casts of the same designation, or by mixed casts that are crushed (
