Common grades of ferritic stainless steel include 409 and 430 grades Duplex This family includes many of the most recent and proprietary alloys created Many duplex grades offer a combination of properties from both austenitic and ferritic stainless steels Duplex stainless steels combine characteristics of the austenitic and ferritic family of alloys to offer benefits from both with fewer downsides often at a lower cost than other steel alloys However cost is only one part of a bigger picture Choosing the right stainless steel is also about how the steel will perform for your intended use 430 stainless steel Ferritic stainless steel for the purpose of decorative for example car accessories The good forming property but poor temperature endurance and corrosion resistance 440 stainless steel The most common application of 440 stainless steel is Jan 26 2020 nbsp 0183 32 Ferritic stainless steel alloys can generally be classified into five groups three families of standard grades Groups 1 to 3 and two families of specialty grade steels Groups 4 and 5 While standard ferritic steels are by far the largest consumer group in terms of tonnage demand for specialty grade stainless steels is increasing steadily History Canadian born engineer Frederick Mark Becket 1875 1942 at Union Carbide industrialised ferritic stainless steel around 1912 on the basis of quot using silicon instead of carbon as a reducing agent in metal production thus making low carbon ferroalloys and certain steels practical quot He discovered a ferrous alloy with 25 27 Chromium that quot was the first of the high

Ferritic stainless steel has very low nickel content higher carbon content and is very corrosion resistant but less strong and durable than austenitic type stainless steel Martensitic Stainless Steel Martensitic type stainless steel contains nickel higher levels of carbon and often molybdenum making it extremely strong and durable with Apr 14 2020 nbsp 0183 32 Duplex is a mixture of austenitic and ferritic stainless steel Thus it has the properties of both its constituents It has high chromium and low nickel concentration With high tensile strength and good weldability duplex stainless steels offer unique advantages It shows good resistance to stress corrosion but not as much as ferritic grades Dec 10 2017 nbsp 0183 32 Ferritic stainless steel has a high amount of chromium and a low amount of carbon The microstructure of ferritic stainless steel is body centered cubic BCC grain structure This structure gives this steel its magnetic properties Austenitic stainless steel is known as non magnetic steel It contains a high level of chromium and nickel along Nov 19 2018 nbsp 0183 32 Duplex Stainless Steel such as grade 2205 Ferritic Stainless Steels Ferritic stainless steels are typically magnetic as they have large quantities of ferrite in their chemical composition Ferrite is a compound of iron and other elements The combination of a ferritic crystal structure with iron makes ferritic stainless steels magnetic Fig 2 Adding 8 nickel to a ferritic chromium stainless steel makes an austenitic chromium nickel stainless steel for example Type 304 stainless steel If less nickel is added to a chromium steel about four or five percent a duplex structure a mixture of austenite and ferrite is created as in 2205 duplex stainless steel

Aug 29 2019 nbsp 0183 32 The second most common form of stainless steel after austenitic alloys As the name implies ferritic stainless steel is magnetic These alloys can be hardened through cold working They also tend to be less expensive because of their reduced nickel content Martensitic Stainless Steels The least common category of stainless steel alloy Ferritic steels are the 400 Grade stainless steels noted for their high chromium content which can range from 10 5 to 27 They have magnetic properties too offers good ductility tensile property stability and resistance to corrosion thermal fatigue and stress corrosion cracking Ferritic Stainless Steel ApplicationsGeneral Properties Duplex 2205 is a two phase ferritic austenitic 22 chromium 3 molybdenum 5 to 6 nickel alloyed stainless steel It is the most widely used duplex stainless steel grade and is characterized by high yield strength double that of the standard austenitic stainless steel grades 2 days ago nbsp 0183 32 Ferritic Stainless Steel Ferritic stainless steel is a type of stainless steel that has only chromium as its additive It contains 10 5 percent to 18 percent of chromium In comparison to the austenitic stainless steel it displays poor fabrication characteristics and poorer corrosion resistance Duplex stainless steels exhibit greater toughness and better weldability than ferritic stainless steel Nilsson 1992 They have higher strength and better corrosion resistance than austenitic stainless steel Atamert and King 1992 Their good engineering performance has led to an increasing number of applications mainly in corrosive

Ferritic stainless steels are the next most widely used type of stainless steel after austenitic stainless steel They contain very low levels of carbon high amounts of chromium but little or no nickel and they are known for their ductility corrosion resistance and magnetic properties 183 Stainless steel grades 410 420 and 440 – martensitic stainless steels Ferritic stainless steels This type of stainless steel is magnetic primarily because it contains large quantities of ferrite in its chemical composition which is a compound of iron and other elements Ferritic stainless steels possess a ferrite microstructure like carbon steel which is a body centered cubic crystal structure and contain between 10 5 and 27 chromium with very little or no nickel This microstructure is present at all temperatures due to the chromium addition so they are not hardenable by heat treatment 1 4003 3CR12 Sheet and Plate Type 1 4003 stainless steel is a utility ferritic stainless steel often used in place of mild steel It offers the benefits of more highly alloyed stainless steels such as strength corrosion and abrasion resistance durability and low maintenance Aug 22 2016 nbsp 0183 32 Duplex stainless steels can provide ferritic stainless steel properties while still maintaining a ductility and a toughness close to austenitic stainless steels Typical Applications Sometimes the best way to find out what grade of stainless steel should be used is to see what has been used in the past
