austeniittisestä

Austeniittisestä is Finnish for “from/relating to austenite,” and it serves as the elative singular form of the adjective austeniittinen, meaning austenitic. It is used in technical Finnish to describe material, structure, properties, or phenomena associated with austenite, typically when the modified noun is in the elative case. For example, austeniittisestä teräksestä means “from an austenitic steel.”

Austenite (austenitti) is a phase of iron-carbon alloys with a face-centered cubic (FCC) crystal structure. In metallurgy, austenite can be stabilized at room temperature in certain alloys by alloying elements such as nickel. The term is widely applied in the context of austenitic stainless steels (for instance, grades like 304 and 316), which are known for high ductility, good formability, and excellent corrosion resistance. In annealed state, these steels are typically non-magnetic, though deformation can induce some magnetic behavior. The Finnish term austenittinen or austeniittinen derives from the English/Latin-root name austenite, itself named after the British metallurgist Sir William Chandler Roberts-Austen.

In usage, austeniittistä occurs in phrases describing aspects of austenitic materials, such as austeniittisestä rakenteesta (“from an austenitic structure”) or austeniittisestä teräksestä (“from an austenitic steel”). The term is mainly confined to engineering and materials-science literature and is less common outside technical contexts.
