Superferritic stainless steels show a BCC structure free of austenite at any temperature. Intermediate ageing temperatures, close to 475 °C, induce a-chromium content modulation and only after long periods of time, it is possible to detect chromium rich α' phase, which is responsible for embrittlement (475 °C embrittlement). In this work, ageing thermal treatments at intermediate temperatures in the superferritic stainless steel DIN 1.4575, have allowed to relate the associated hardness increase with time and temperature by means of a relationship that is compatible with a thermally activated process. After quenching from ageing temperature, twinning formation has been observed, and the extent of twinning is proportional to the increase in hardness, showing in this way that twinning density is proportional to embrittlement level.
