What is Ferritic Stainless Steel and What all are its Applications?
Ferritic Stainless Steel is a grade that contains over 12% of chromium and is magnetic, high – chromium steels that have low carbon content. It differs from other forms of steel in two critical regards; its molecular grain structure and its chemical composition.
This type is well known for their good ductility, corrosion resistant and stress corrosion cracking. It is commonly used in automotive applications, kitchenware and industrial equipment.
Ferritic is the next most widely used type of S.S after Austenitic type. Ferritic is actually defined as straight chromium non-harden class of alloy.
Here are some characteristics
• High in Chromium
• Cannot be hardened or strengthened by heat treatment
• Magnetic Property
• Good resistance to stress-corrosion cracking
• Have better engineering property
• Less Expensive
• Good ductility and formability
• Low Thermal expansion
• High Thermal Conductivity
• High Oxidation Resistant

Ferritic stainless steels ...
... are classified into 400 series, usually with 10% to 30% chromium content, and are more often chosen for their excellent corrosion resistance and elevated temperature oxidation resistance. With greater strength than carbon steels, ferritic provide an advantage in many more applications where thinner materials and reduced weight are necessary, like in automotive emission control systems.

Types of Ferritic stainless-steel Available
There are two main forms of ferritic grades available in stainless-steel structural profiles. They are types 409 and 410S. These two types is laser welded, so Stainless Structural can produce any of our common structural shapes likewise as special shapes in these alloys through our laser fusion method.
1. Grade 409
Grade 409 could be a stabilized ferritic stainless-steel. That means, titanium and chromium stabilize it, with eleven percent chromium being the minimum amount in need for the passive surface that provides stainless-steel its corrosion resistance. Grade 409 provides medium strength, good formability, and weldability but it doesn't have an identical surface appearance.
2. Grade 410S
Grade 410S is ferritic stainless-steel that's a low carbon variation of ferritic type 410 chrome steel. Because of the lower level of carbon and also the addition of titanium and/or columbium, this alloy minimizes austenite formation at higher temperatures.
Application

Ferritic stainless-steel are mainly employed in making automotive parts, industrial machinery, and kitchen wares as they readily undergo cold working and deep drawing operations.
The magnetic properties of ferritic grades could be a major advantage and enabler for several of their applications. Fastening parts and heating, for instance, both make use of this property within the production of induction cookers and magnetic fasteners.
The corrosion resistance of some ferritic stainless steels is sufficient to switch austenitic steel 304, and that they may be employed in the assembly of dishwashers, kitchen sinks, and food processing equipment.
Ferritic stainless steel is further divided into five distinct groups. These groups vary in terms of the precise amounts of various metals they contain, also as their particular performance attributes.
Group 1: Are among the smallest amount expensive sorts of stainless-steel. They include extremely low chromium levels, meaning that they have a tendency to assemble a layer of localized surface rust over time.
Group 2: Are the foremost commonly used type. Due to their higher chromium levels, these steels possess greater corrosion resistance. Generally used for building features and interior appliances.
Group 3: Are well-known for their simple forming and welding. They're suitable for a large range of applications.
Group 4: Contain higher amounts of molybdenum, further improving their corrosion resistance. This kind of steel is usually used for high-moisture applications like exhaust systems and hot water tanks.
Group 5: It have the best chromium levels, giving them a degree of corrosion resistance that's unmatched by almost a few of other metals.
