F73

F73 is a type of stainless steel, specifically a grade of austenitic stainless steel. It is part of the 200 series of stainless steels, which are known for their excellent corrosion resistance and good formability. F73 is characterized by its high nickel content, which contributes to its austenitic structure and resistance to corrosion. This grade is often used in applications where both strength and corrosion resistance are required, such as in chemical processing equipment, food handling equipment, and marine applications.

The chemical composition of F73 typically includes iron as the base element, with significant amounts of chromium, nickel, and manganese. The exact composition can vary slightly depending on the specific manufacturer and intended use, but it generally falls within the following range: 17-19% chromium, 9-12% nickel, and 1-2% manganese. The remaining percentage is primarily iron, with small amounts of other elements such as carbon, silicon, and phosphorus.

F73 stainless steel is known for its excellent resistance to corrosion, including resistance to pitting, crevice corrosion, and stress corrosion cracking. It also has good mechanical properties, including high tensile strength and good ductility. These properties make F73 suitable for a wide range of applications, from structural components to decorative finishes.

In terms of processing, F73 can be welded using standard stainless steel welding techniques, although care must be taken to avoid heat-affected zone issues that could compromise its corrosion resistance. It can also be machined, polished, and fabricated using conventional methods for stainless steel. Overall, F73 is a versatile and reliable material for applications requiring both strength and corrosion resistance.
