Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Ferrous slags are non oxidising

Key value for chemical safety assessment

Oxidising properties:

Additional information

Ferrous slags are inert inorganics with all relevant analytes in their most stable oxidation state. Ferrous slags are formed at temperatures of >1000 °C and, thus, are free of any material which could exothermically react with combustible material under standard conditions.

Justification for classification or non-classification

Based on observation, knowledge of the manufacturing method, and analytical information, ferrous slags are not oxidising
