ISO 10387-1994 PDF

Full title and description

ISO 10387:1994 — Metal chrome — Specification and conditions of delivery. Specifies requirements and conditions of delivery for metal chrome (chromium metal) normally supplied for alloying special steels and other alloys, including requirements for chemical composition, particle-size classes, consignment constitution, sampling and testing, packaging and delivery documentation.

Abstract

This International Standard defines minimum chromium content and limits for common impurities, designations for production methods (for example electrolytic, aluminothermic, refined), particle-size classes and tolerances, consignment and delivery rules, and sampling and testing procedures and documentation required for contractual supply of metal chrome for metallurgical use. It also references relevant normative standards for sieving and sampling.

Scope

Applies to metal chrome supplied for alloying special steels and other alloys. The standard covers what information must be included in orders, chemical composition designations, particle-size classes and tolerances, consignment constitution (single melt or graded lots), supplier and purchaser testing and arbitration procedures, packaging, storage and transport considerations, and the required analysis certificate accompanying each consignment.

Key topics and requirements

• Minimum chromium content and grade designations (metal chrome defined as an alloying material with minimum ~98 % Cr by mass).
• Limits for common impurities and optional gas limits for certain electrolytic grades.
• Particle-size classes (ranges for lumps and crushed/screened particles) and sieving references (ISO 565).
• Ordering information requirements: quantity, consignment constitution, chemical composition/designation, particle-size class, analysis and packing requirements.
• Sampling and testing rules, supplier certificates and purchaser check testing (sampling prepared per ISO 3713 or agreed methods).
• Packing, contamination control, storage and transport requirements with reference to applicable transport regulations.

Typical use and users

Used by steelmakers, ferroalloy producers, alloy manufacturers, material procurement and quality control laboratories to specify and accept chromium metal feedstock for alloying processes. Also used in contractual procurement documentation and by testing laboratories carrying out compositional and particle-size verification.

FAQ

Q: What is this standard?

A: ISO 10387:1994 is an International Standard that specifies the requirements and conditions of delivery for metal chrome supplied for alloying special steels and other alloys.

Q: What does it cover?

A: It covers chemical composition and grade designations (notably a minimum chromium content typically around 98 %), impurity limits, particle-size classes and tolerances, consignment constitution, ordering information, sampling and testing procedures, packing, and delivery documentation.

Q: Who typically uses it?

A: Steelmakers, ferroalloy and alloy producers, purchasers and procurement teams, material testing and quality control laboratories, and anyone specifying or accepting chromium metal for metallurgical use.

Q: Is it current or superseded?

A: The ISO catalogue entry indicates ISO 10387:1994 remains published and was last reviewed/confirmed in ISO’s review cycle (confirmed in 2022), so this edition is the current published version unless superseded by a later ISO amendment or new edition after that review. Users should check the ISO catalogue or their national body for any changes after 2022.

Q: Is it part of a series?

A: It is one of the ferroalloys delivery/specification standards prepared by ISO/TC 132; other related ferroalloy standards (for example for ferroboron and other alloying additives) form the broader family of ferroalloy specifications.

Q: What are the key keywords?

A: metal chrome, chromium, ferroalloy, alloying material, delivery conditions, chemical composition, particle size, sampling, testing, ISO 10387.
