There are several types of stainless steel, including Austenitic, Ferritic, Martensitic, Duplex, and Precipitation Hardening.
Austenitic stainless steel is the most common type and contains nickel and chromium. It is non-magnetic and has good corrosion resistance, making it suitable for a wide range of applications, including kitchen utensils, medical equipment, and food processing equipment.
Ferritic stainless steel contains chromium but little or no nickel. It is magnetic and has good corrosion resistance, making it suitable for automotive and transportation applications, as well as heat exchangers and boilers.
Martensitic stainless steel contains chromium and low levels of nickel. It is magnetic and can be hardened through heat treatment, making it suitable for cutting tools, valves, and pumps.
Duplex stainless steel contains equal parts Austenitic and Ferritic stainless steel. This makes it stronger and more corrosion resistant than other types of stainless steel. It is used for applications such as chemical processing, oil and gas, and marine environments.
Precipitation Hardening stainless steel is a type of stainless steel that is heat treatable to a high level of strength and hardness. It is used in applications such as aerospace and defense.
In general, stainless steel is known for its corrosion resistance, strength, and durability. It is used in a wide range of applications, including construction, transportation, medical equipment, and kitchen utensils.
