Types of Stainless Steel
Austenitic stainless steel
Austenitic stainless steel is the most common type of stainless steel, accounting for almost two-thirds of all stainless-steel manufacturing. They have a face-centered cubic crystal structure with an austenitic microstructure.
This microstructure is obtained by alloying steel with enough nickel, manganese, and nitrogen to preserve an austenitic microstructure at all temperatures, from cryogenic to melting.
For this reason, austenitic stainless steels cannot be hardened by heat treatment since they have the same microstructure at all temperatures.
Austenitic stainless steels are further classified into two groups: the 200 series and the 300 series.
- The 200 series are chromium-manganese-nickel alloys that optimize the usage of manganese and nitrogen while minimizing the use of nickel. Because of the nitrogen addition, they have roughly 50% higher yield strength than 300 series stainless steel sheets.
- The 300 series are chromium-nickel alloys with an austenitic microstructure achieved nearly entirely through nickel alloying; some extremely highly alloyed grades include some nitrogen to reduce nickel requirements. The 300 series is the largest and most widely used group.
Austenitic steels are quite well known for their weldability and malleability. They are commonly used for kitchen cutlery and storage components, but they are also known for their toughness.
They are normally particularly corrosion resistant. This makes them suitable for a wide range of applications in corrosive environments. Alloys 304 and 904L are examples of common austenitic stainless steels.
The one significant downside of austenitic stainless steel is its high cost.
- Ferritic
Ferritic stainless steels have a ferrite microstructure, which is a body-centered cubic crystal structure, similar to carbon steel, and contain between 10.5 percent and 27 percent chromium with very little or no nickel.
Because of the chromium addition, this microstructure is constant at all temperatures, therefore they cannot be hardened by heat treatment.
They cannot be cold worked to the same extent as austenitic stainless steels. They have a strong magnetic field.
Weldability is improved by the addition of niobium (Nb), titanium (Ti), and zirconium (Zr) to Type 430.
They are less expensive than austenitic steels due to the lack of nickel and are used in a variety of goods, including:
- Automobile exhaust pipes (Type 409 and 409 Cb are used in North America; stabilized grades Type 439 and 441 are used in Europe)
- Architectural and structural applications (Type 430, which contains 17 percent Cr)
- Construction elements such as slate hooks, roofing, and chimney ducts
- Solid oxide fuel cells with power plates working at temperatures about 700 °C (1,292 °F) (high-chromium ferritic containing 22 percent Cr)
Ferritic stainless steels are stainless steels that include trace levels of carbon. Carbon contents in ferritic stainless steels typically do not surpass 0.10 percent.
While additional minerals can be added to these steels (molybdenum is a frequent additive), chromium is the primary component.
Ferritic stainless steels are magnetic and are widely utilized because of their resistance to stress corrosion cracking.
They are widely used for applications that will come into contact with potentially corrosive materials. Automobile components, cooking cookware, and industrial entities are examples of these products.
Duplex stainless steels
Duplex stainless steels contain a mixed microstructure of austenite and ferrite, with an optimum ratio of 50:50, while commercial alloys may have ratios as low as 40:60.
They have greater chromium (19–32%) and molybdenum (up to 5%) levels and lower nickel contents than austenitic stainless steels.
Duplex stainless steels are fundamentally ferritic and austenitic stainless steels combined. They are stronger than ferritic and austenitic stainless steels but contain less nickel than austenitic steels, therefore, less expensive than austenitic steels.
The yield strength of duplex stainless steels is nearly double that of austenitic stainless steel. In comparison to austenitic stainless-steel Types 304 and 316, their mixed microstructure gives enhanced resistance to chloride stress corrosion cracking.
Due to its corrosion resistance, duplex grades are typically classified into three sub-groups: slim duplex, standard duplex, and super duplex.
Duplex stainless steels’ qualities are accomplished with a lower overall alloy content than comparable-performing super-austenitic grades, making their use cost-effective in many applications.
The pulp and paper sector were among the first to employ duplex stainless steel substantially.
The oil and gas industry is the greatest customer today, and it has pushed for higher corrosion resistant grades, resulting in the development of super duplex and hyper duplex grades.
Recently, the less expensive (but somewhat less corrosion-resistant) lean duplex has been developed, mostly for structural applications in building and construction (concrete reinforcing bars, bridge plates, coastal works) and the water sector.
The offshore oil industry makes extensive use of duplex stainless steel. This is primarily owing to its corrosion resistance, which allows it to endure the corrosive nature of salt water for extended periods of time.
Duplex stainless steels, which are fairly malleable and weldable, can be molded to form a variety of various components.
S31803 stainless steel and S32205 stainless steel are two of the more prevalent forms of duplex stainless steel.
Martensitic stainless steels
Martensitic stainless steels are useful as stainless engineering steels, stainless tool steels, and creep-resistant steels because they have a wide range of qualities.
Because of their low chromium concentration, they are magnetic and not as corrosion-resistant as ferritic and austenitic stainless steels.
Martensitic stainless steels are functionally identical to ferritic stainless steels, with the main significant changes being their carbon contents.
While carbon percentages in ferritic stainless steel are less than 0.10 percent, carbon percentages in martensitic stainless steel are around 1%.
This disparity in carbon percentages is significant because it allows for extensive hardening of martensitic stainless steels.
This steel is often utilized in circumstances that require high strength but just mediocre corrosion resistance. It is commonly used in valves and pumps, but it has numerous other applications as well.
Alloy 431 and 420S45 are two martensitic stainless steels.

The most common form of stainless steel contains up to 16% chromium, 8% nickel and a maximum of 1% carbon.
The iron-based alloyed material can be formed into a variety of different shapes and sizes using specific heat treatments to alter the hardness, strength, ductility and temper.
These variations and treatment are used to create different grades and classifications with different applications.
What is the best grade stainless steel?
The most common grades of stainless steel are 304, 316 and 321. They are often referred to as type 304, type 316 and type 321.
What is a duplex stainless steel?
Duplex stainless steels contain a composition of roughly equal amounts of austenite and ferrite, which is different than the equilibrium monosteel formed by the atomic distribution of microstructure elements within a steel matrix.
How can I tell if my stainless steel is 304 or 316?
The most common grades of stainless steel are 304, 316 and 321. They are often referred to as type 304, type 316 and type 321.
Many companies alloy their stainless steel with other metals to achieve the desired properties for whatever application they are creating it for.
For example, a common alloy is grade 316L which is composed of roughly 2% aluminium, 0.5% silicon and a maximum of 0.10% carbon.
Which is more expensive 304 or 316 stainless steel?
316 has at least 2.0 percent molybdenum, which makes it far more corrosion resistant than 304. However, because molybdenum is a more expensive element, 316 is normally a more expensive grade of metal.

Is 304 or 316 stainless steel betters?
While both 304 and 316 stainless steels are good for corrosion resistance, strength, welding, and heat resistance, 316 stainless steels have a marginal advantage in all of these categories due to variations in alloying elements.
What’s the difference in pricing between 304 and 316 stainless steels?
304 stainless is also less expensive than 316 stainless, which contributes to its popularity and broad use.
Stainless 316 is more expensive because it has better corrosion resistance, particularly against chlorides and chlorinated solutions.
304 stainless steel Vs 316 stainless steel
The most popular austenitic stainless-steel grades are 304 and 316. In appearance, the two are indistinguishable, and the few tests available to identify them involve either toxic substances (in the case of a molybdenum drop test) or expensive equipment (such as positive material identification).
316 has at least 2.0 percent molybdenum, which makes it far more corrosion resistant than 304.
However, because molybdenum is a more expensive element, 316 is normally a more expensive grade of metal.
The majority of stainless steel 304 applications are related to its high concentration of Chromium, which provides the alloy with outstanding corrosion resistance.
These applications include: producing kitchen appliances such as refrigerators and dishwashers, heat exchangers, commercial food processing equipment and kitchen fittings such as sinks and splashbacks, saucepans, cutlery and flatware, and nuts, bolts, screws, and nuts.
316 stainless steel was originally designed for use in paper mills. It is now widely utilized in a variety of applications, including food, chemical, and petroleum production and processing equipment, laboratory benches and equipment, boat fitting, mining screens, tubing, and medical implants.
Is 304 or 430 stainless better
When it comes to corrosion protection, homeowners may find that 430 is just as good as 304.
However, some designs necessitate formability and weldability, and 304 is the obvious victor in these areas. 430, on the other hand, is slightly easier to process than 304.
