Novel oxide dispersion strengthened steels obtained by high productivity casting process with innovative injection of suitable special powders

Objective

The objective of the proposal is to develop a new generation of stainless steels obtained by means of dispersion of fine ceramic particles into the metal matrix. The dispersion is realised during the continuous casting process by injecting suitable developed powders into the melt stream.

These stainless steels will have:
- A modified as-cast structure, as the particles promote an equi-axed solidification by heterogeneous nucleation
- Increased mechanical properties at both room and high temperature
- Properties insensitive to post heat treatments (e.g. welding)

The development activity will be performed on one ferritic, AISI 439 and one austenitic, AISI 301LN stainless grades and on one austenitic special steel. The project and will take into account the whole manufacturing cycle (casting, hot rolling, annealing, cold rolling and annealing) even though the heart of the innovation concerns the injection of the ceramic powder into the melt stream during the casting process.

The effect on the mechanical properties, both at room and at high temperature, will be verified by means of appropriate testing for AISI 439. For AISI301LN, the mechanical properties will only be tested at room temperature.
