What is the structure of ferrite and martensite?What is the structure of ferrite and martensite?Body centred cubic crystalline structure of ferrite and martensite. Ferritic steels are made up of ferrite crystals, a form of iron which contains only a very small amount (up to 0.025%) of carbon. Ferrite absorbs such a small amount of carbon because of its body centred cubic crystal structure - one iron atom at each corner, and one in the middle.What Is The Difference Between Ferritic, Austenitic chemical composition of austenitic ferritic martensitic4.8/5(2.4K) 5 minsBrand AccuStainless Steel Chemical composition (Daido grades)

Ferritic stainless steels (e.g. grades 1.4512 and 1.4016) consist of chromium (typically 12.5% or 17%) and iron. Ferritic stainless steels are essentially nickel-free. These materials contain very little carbon and are non-heat treatable, but exhibit superior corrosion resistance to martensitic stainless steels Welding of Ferritic / Martensitic Stainless Steels - TWICarbon and nitrogen, however, are two elements that promote the formation of austenite so, as the percentage of carbon and/or nitrogen increases, the ferritic steel can be designed to transform, wholly or partially, to austenite before transforming back to ferrite.
