317 stainless steel is an austenitic stainless steel with high levels of chromium, nickel, and molybdenum. This steel type is highly resistant to corrosion and is especially suitable for harsh environments such as chemical processing, marine, and high-temperature applications.

In addition to its excellent corrosion resistance, 317 stainless steel has good mechanical properties, such as high tensile strength, good ductility, and excellent toughness. It is highly resistant to stress corrosion cracking and is often used in applications that require resistance to chlorides and sulfides.

Common applications for 317 stainless steel include chemical processing equipment, pulp and paper industry, food and beverage processing, pharmaceutical industry, and petrochemical industry. It is also used in high-temperature applications, such as heat exchangers, furnace parts, and boilers.
