Series of Stainless Steels

These are different series of Stainless Steel Alloys categorized based on their composition and characteristics:

 1 Austenitics (S300 Series): These Stainless Steels are characterized by their austenitic crystal structure, which provides excellent corrosion resistance and high toughness, even at low temperatures. They are non-magnetic and have good weldability and formability. Common grades in the S300 series include 304 and 316 Stainless Steel, which are widely used in various industries including Food Processing, Chemical Processing, and Medical Equipment.

 2 Austenitics containing Manganese (S200 Series): This series of Stainless Steels contains higher levels of manganese compared to the S300 series. Manganese helps improve the strength and formability of the Alloy while maintaining good corrosion resistance. These Alloys are often used in applications requiring enhanced formability and deep-drawing capabilities.

 3 Duplex, Ferritics (S400 Series) and Martensitics: This series includes Stainless Steels with different microstructures and properties. Each series and grade within these categories offers specific properties and is chosen based on the requirements of the application, including corrosion resistance, strength, formability, and magnetic properties.

 • Duplex Stainless Steels: These Alloys have a mixed microstructure of austenite and ferrite, offering a combination of high strength and corrosion resistance. They are commonly used in applications requiring high strength and resistance to chloride stress corrosion cracking, such as in Marine Environments and Oil and Gas processing.

 • Ferritic Stainless Steels: These Alloys are characterized by a ferritic crystal structure, providing good corrosion resistance and high-temperature strength. They are non-hardenable by heat treatment and are often used in automotive Exhaust Systems, Architectural Applications, and Kitchen Equipment.

 • Martensitic Stainless Steels: These Alloys have a martensitic crystal structure and are known for their high strength and hardness. They can be hardened by heat treatment and are commonly used in applications requiring wear resistance, such as Cutting Tools, Knives, and Surgical instruments.
