A ferrous metal must be based on iron, not merely contain iron. Examples of ferrous metals include steel, stainless steel, galvanized steel, cast iron, and wrought iron.
Eksperdi sõnul on Tallinna Tehnikaülikoolis loobutud vanematest venemõjulistest nimetustest "mustmetall" ja "värviline metall" ja mindud üle nimetustele "raudmetall" ja "mitteraudmetall" (saksa, prantsuse, inglise keele järgi), mida kasutatakse nii teaduspublikatsioonides kui õppetöös.
Production and processing of metals: metal ore roasting or sintering installations, installations for the production of pig iron or steel (primary or secondary fusion) including continuous casting with a capacity exceeding 2.5 Mg/hour, installations for the processing of ferrous metals (hot rolling mills > 20 Mg/hour of crude steel).
