What is the difference between 316 and 347 stainless steel?

The main differences between 316 and 347 stainless steel are:

  1. Composition: 316 stainless steel contains chromium, nickel, and molybdenum, while 347 stainless steel contains chromium, nickel, columbium (niobium), and tantalum.
  2. Temperature Resistance: 347 stainless steel has improved high-temperature stability and resistance to sensitization and intergranular corrosion compared to 316 stainless steel.
  3. Applications: 316 stainless steel is widely used in various industries for its general corrosion resistance, while 347 stainless steel is primarily utilized in high-temperature applications requiring resistance to sensitization and intergranular corrosion.
  4. Weldability: Both alloys have good weldability, but 347 stainless steel has added elements to prevent sensitization and intergranular corrosion during welding, even in high-temperature applications.

Overall, 316 stainless steel is commonly used for its corrosion resistance, while 347 stainless steel is preferred in applications with high-temperature conditions and a need for resistance to sensitization and intergranular corrosion.

Does 347 stainless steel rust?

Actually, 347 stainless steel is highly resistant to rust and corrosion due to its composition and the formation. While it is not entirely immune to corrosion, it exhibits excellent corrosion resistance under normal conditions. Proper maintenance and avoiding exposure to harsh environments are important to maintain its corrosion-resistant properties.
