Physical Properties of Low Chromium Ferritic Stainless Steel 0Cr13Al(AISI405)

Physical properties of low chromium ferritic stainless steel 0Cr13Al (AISI405)

Low chromium ferritic stainless steel 0Cr13Al (AISI 405) is an economic and versatile stainless steel characterized by its low carbon content and good corrosion resistance. The low carbon content reduces the amount of precipitated carbides and helps produce components with more uniform dimensional tolerances. Additionally, it has excellent loil and oxide scale resistance, which makes it particularly suitable for high temperature applications.

The mechanical properties of 0Cr13Al (AISI 405) also make it suitable for a wide range of applications. It has a nominal tensile strength of 450 to 520 MegaPascals (MPa) and yield strength of 210 to 240 MPa, with elongation and reduction of area values of 40 to 50%. Its strength can also be improved in higher-temperature treatments.

0Cr13Al (AISI 405) also has good toughness, allowing it to withstand high stresses without fracturing. Its toughness is affected by the grain size, with finer grain sizes resulting in higher toughness. Additionally, its impact energy values can reach as high as 43 Joules at a temperature of -100°C, resulting in very good performance in low-temperature applications.

Due to its low chromium content, 0Cr13Al (AISI 405) is not as corrosion-resistant as other ferritic stainless steels. Its corrosion resistance is further decreased when it is exposed to chloride environments, making it unsuitable for applications in such environments. Despite this, it is commonly used in indoor, non-corrosive atmospheres.

Finally, 0Cr13Al (AISI 405) has excellent machinability and polishability for parts requiring high surface quality and detailed parts. It is mainly used to produce automotive parts, hardware, kitchen utensils, and various valves.

In conclusion, the low chromium ferritic stainless steel 0Cr13Al (AISI 405) is an economic and versatile stainless steel. It has excellent mechanical properties and corrosion resistance, allowing it to be used in a wide range of applications. Its good machinability and polishability make it suitable for producing parts requiring high surface quality and detailed parts.
