5 Classification

5.1 Alloy stainless steel depending on structure, are divided into classes:

— martensitic steel with the main structure of martensite;

— martensite-ferritic steel containing in the structure apart of martensite of at least 10% ferrite;

— ferritic — steel, having a ferrite structure (without transformations);

— austenite-martensitic — steel, having a structure of austenite and martensite, the amount of which can be changed within wide limits;

— austenite-ferritic — steel, having a structure of austenite and ferrite (ferrite is more than 10%);

— austenitic steel having a structure of stable austenite.

The steel division into classes according to structural features is conditional, as it implies only one heat treatment, namely, air cooling after high-temperature heating (900°C) samples of small size. Therefore, structural variations in the acceptance become a symptom of are not.
