DENSITY OF STEEL


The density of steel varies but usually ranges between 7,750 and 8,050 kg/m3 (484 and 503 lb/cu ft). Following steel density chart shows density values for some of the plain carbon steels and stainless steels.

Steels are iron and carbon alloys which may also contain other alloying materials. There are too many types of steel alloys with different composition and heat treatment.
