317L stainless steel is an austenitic stainless steel that contains a low carbon content and higher amounts of molybdenum and nickel compared to 304 stainless steel. The low carbon content of 317L reduces the risk of intergranular corrosion caused by sensitization during welding or high-temperature exposure.
The higher nickel and molybdenum content of 317L provide superior resistance to corrosion in harsh environments, particularly those containing chlorides or other halides. This makes it suitable for use in chemical processing, pulp and paper manufacturing, and oil and gas refining applications.
317L stainless steel offers excellent toughness, strength, and formability, and is easy to fabricate using standard methods. It can be welded using common welding techniques, and is often used to fabricate complex shapes and components.
Some of the key properties of 317L stainless steel include:
Corrosion resistance: 317L offers superior corrosion resistance in harsh environments, particularly those containing chlorides or other halides.
High-temperature resistance: 317L can withstand high temperatures and thermal cycling without losing its corrosion resistance properties.
Strength and toughness: 317L offers good strength and toughness, making it suitable for use in demanding applications.
Fabricability: 317L is easy to fabricate using standard methods, and can be welded using common welding techniques.
Overall, 317L stainless steel is a versatile and reliable material that is well-suited for use in a wide range of applications where superior corrosion resistance and high-temperature performance are required.
