Physical Properties Of Stainless Steel Sheet
- Aug 06, 2018 -

Compared with carbon steel


1, the density of


Carbon steel is slightly denser than ferrite and martensitic stainless steel, and slightly less dense than austenitic stainless steel.


2. Resistivity


The resistivity was increased by carbon steel, ferrite type, markov type and austenitic type stainless steel.


3. The rank of linear expansion coefficient is similar. Austenitic stainless steel is the highest and carbon steel is the smallest.


4. Carbon steel, ferrite and martensite stainless steel have magnetic properties, while austenitic stainless steel has no magnetic properties. However, magnetic properties will be generated when the martensite transformation is formed by cold processing and hardening.


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


1) high resistivity, about 5 times of carbon steel.


2) large linear expansion coefficient, 40% greater than carbon steel, and the value of linear expansion coefficient increases with the increase of temperature.


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