AISI 405 Ferritic Stainless Steel Chemical Composition Properties, Grades, Chart and Pdf

AISI 405 refers to the standard specification of a duplex stainless steel which is highly resistant to corrosion as well as has the ability to retain strength at higher temperatures. The light spectrum range of chromium is commonly composed of 11.5% to 14.5% chromium along with up to 1% manganese, which helps to enhance superior oxidation resistance and general corrosion in almost all kinds of environments such as mild atmospheres, steam, and others. Moreover it is readily weldable and formable, this allows its application in a number of places such as automotive exhaust systems, heat exchangers and industrial equipment among others. AISI 405 has all needed properties with different grades that is a factional point in the industries which require the high-level of durability and reliability. Charts and PDF files made in such a way to include the material entire properties will be widely accessible to engineers and designers, allowing them to choose the right material and develop the application.

AISI 405 Ferritic Stainless Steel Chemical Composition And Grade Table

The AISI 405 ferritic stainless steel is a material belonging to the family of stainless steel characterized by the unique chemical composition which is responsible for its performance. Normally made of chromium (12-14%), manganese (1%), silicon (1%), sulfur (0.03%), phosphorus (0.04%), and carbon (0.08%). This specific alloy poses its corrosion resistance against oxidation and scathe, which are some of the requirements for industrial application. AISI 405 is included in the group of alloys that are ferritic stainless steel and are characterized by various properties and applications based on their grades. A table with a brief description of the chemical composition and grades is shown to convey the possibility of using the material for different engineering applications.
