Austenitic Stainless Steel: This type of stainless steel is non-magnetic and is known for its excellent corrosion resistance.    It contains high levels of chromium and nickel and is commonly used in applications that require a high level of cleaning and hygiene, such as food processing equipment and medical equipment.

      Ferritic stainless steel: Ferritic stainless steel is magnetic and has lower carbon content than austenitic stainless steel.    It is highly resistant to stress corrosion cracking and is commonly used in automotive and construction applications.    Martensitic Stainless Steel: This stainless steel is known for its high strength and hardness.    It contains a higher amount of carbon than other stainless steels, which gives it its characteristic strength.

      Martensitic stainless steels are commonly used in tableware, surgical instruments and turbine blades.    Duplex Stainless Steel: Duplex stainless steel has a mixed microstructure of austenite and ferrite, providing a balance of strength and corrosion resistance.    It is commonly used in chemical processing, oil and gas, and marine applications.    Precipitation Hardened Stainless Steel: This type of stainless steel can be strengthened by heat treatment to achieve high strength and corrosion resistance.    It is commonly used in aerospace components and high-performance engineering applications.

      Each class of stainless steel has unique properties that make it suitable for specific applications, and understanding these classifications can help select the right material for a given use case.
