Stainless Steel Physical Properties
Nov 20, 2018

The physical function of stainless steel is comparable to that of carbon steel. The density of density carbon steel is slightly higher than that of ferrite and martensitic stainless steel, and slightly lower than that of austenitic stainless steel. 2. Resistivity resistivity is carbon steel and ferrite type. , Martensitic and austenitic stainless steels are in increasing order; 3. The order of linear expansion coefficient is similar, austenitic stainless steel is high and carbon steel is the smallest; 4. Carbon steel, ferritic and martensitic stainless steel are magnetic Austenitic stainless steel is non-magnetic, but its magnetic properties will occur when it is cold worked hard to form a martensite transformation. It can be removed by thermal treatment to restore its non-magnetic properties. Compared with carbon steel, austenitic stainless steel has the following characteristics: 1) High electrical resistivity, about 5 times that of carbon steel. 2) The coefficient of linear expansion is 40% higher than that of carbon steel, and the temperature increases, and the value of linear expansion coefficient also increases. 3) Low thermal conductivity, about 1/3 of carbon steel.
