Terästen

Terästen is a Finnish term used primarily as the genitive plural of teräs, meaning steel. It denotes “of steels” or “steel items” in contexts where multiple steel grades, products, or batches are discussed. The form is used in technical, industrial, and catalog language, often in compound nouns such as terästen laatu (the quality of steels), terästen hinta (the price of steels), terästen tuotanto (the production of steels), and terästen standardit (standards for steels).

Etymology and morphology: The word teräs “steel” forms the genitive plural with the suffix -ten, producing terästen. The corresponding singular genitive is teräksen. Finnish inflection patterns vary with noun classes, and teräs exemplifies the -s nouns that take -en/-ksen in genitive, or -ten in genitive plural.

Usage note: Terästen does not denote a single material or a specific brand; it is a grammatical form used when speaking of steels in general or of multiple steel kinds.
