what do you think about producebility of low density steel? for example: can density of 1020 steel (or ony others) be decreased without any loss of other properties.

1. A method has been developed for magnetic phase analysis of Fermanal type alloys as-quenched and after aging.
2. The upper limit of alloying to ensure the optimal mechanical properties was determined more precisely for steel 9G28Yu9MVB. For rods aged at 550°C for 16 h the aluminum content should not exceed 9.2% and the carbon content 0.92%.
3. To ensure the optimal mechanical properties of the deformed metal it is necessary to obtain a fine-grained single-phase austenitic structure after quenching. The amount of hardening phase after quenching should not exceed 15–20% (saturation magnetization around 1600 G).

If a material has a lower density than steel, then it isn't steel.
