What is the density of carbon steel

2020-06-04

Density, formerly known as specific gravity, is the mass (weight) of material per unit volume. 

The following material density unit is t/m3 (ton /m3), or g/cm3 (g/cm3).If kg/m3 (kg/m3) is used, multiply the value by 1000 (*103). 

Carbon steel :7.81-7.85, cast steel :7.8, alloy steel: 7.9, nickel-chromium steel :7.8

The density of carbon steel is slightly higher than that of ferritic and Martensitic stainless steel, but slightly lower than that of Austenitic stainless steel.The resistivity of carbon steel, ferritin type, Martensite type and austenitic type stainless steel sequence increase;The order of linear expansion coefficient is similar. Austenitic stainless steel is the highest while carbon steel is the lowest.Carbon steel, ferritin type and Martensitic stainless steel type magnetic, austenitic stainless steel type non-magnetic, but its cold working hardening into tensitic phase transition will produce magnetic, heat treatment can be used to eliminate this martensitic structure and restore its non-magnetic.

Compared with carbon steel, austenitic stainless steel has the following characteristics:

1) High resistivity, about 5 times that of carbon steel.

2) Large linear expansion coefficient, 40% larger than that of carbon steel, and with the increase of temperature, the value of linear expansion coefficient increases correspondingly.

3) Low thermal conductivity, about 1/3 of carbon steel.
