bg4.png [Discussion Post 21] Regarding the density of dual-phase steel - why is it lower than carbon steel?
The density of ductile iron is gray cast iron: 6.6-7.4, ductile iron: 7.3, and malleable cast iron: 7.2~7.4. Dual phase steel is ferrite and austenite. So low
The atomic weight of the contained elements is smaller than that of iron, so the density is smaller.
Generally speaking, carbon steel is 7.85 and stainless steel is 7.93. However, it is puzzling that dual-phase steel is lower than carbon steel.
It means that they are expanded according to the component elements and compared with iron. Duplex steel actually has many advantages, and the unit price is about 30,000 per ton.
For example, the density of the precipitation hardening phase of some precipitation hardening stainless steels is small. Ferritic stainless steels with high chromium content have low density. Austenitic stainless steels with high nickel and manganese content have high density.
Based on what you said, it will be easier to compare the periodic table.
