316 Stainless Steel Coil and Sheet

316 stainless steel is an austenitic chromium-nickel stainless steel that contains molybdenum, which gives it excellent corrosion resistance in highly corrosive environments, but also increases its cost. Due to its superior performance in seawater, it is known as "marine-grade" stainless steel. Because of its excellent corrosion resistance, 316 is also used in the medical industry for surgical implants and instruments. It can also be found in pharmaceutical equipment, heat exchangers, and food processing equipment.

316 or Others?

Stainless steel grade 316 is widely utilized, making it challenging to differentiate between 316 and other stainless steel grades. Sanmei Metal provides guidance to help you make the right selection.

Takeaway

When choosing stainless steel grades, consider the specific application requirements:

306/304: General purposes with less critical corrosion resistance needs.

316: High corrosion resistance, ideal for marine and chemical environments.

316L: Best for welding-heavy applications due to lower carbon content.

321: Suitable for high-temperature applications with frequent temperature changes.

440C: High hardness and wear resistance for cutting tools and bearings.

F316: Used in casting components for pumps and valves.

F316 Stainless Steel vs. 316

Composition and Application:

  • F316 Stainless Steel: Typically contains more carbon and is used for cast products.
  • 316 Stainless Steel: Standard for wrought products with 2-3% molybdenum for corrosion resistance.

Applications:

  • F316: Used in pump and valve components.
  • 316: Commonly used in the fabrication and manufacturing of corrosion-resistant equipment

416 Stainless Steel vs. 316

416 stainless steel is a martensitic stainless steel, while 316 stainless steel is an austenitic stainless steel. 416 has higher hardness and strength compared to 316, making it more suitable for applications requiring wear resistance. However, 316 has superior corrosion resistance, especially in chloride-containing environments like seawater, due to the addition of molybdenum. Therefore, 316 is more suitable for marine environments, medical devices, and chemical processing equipment, but it is also more expensive than 416. Additionally, 416 is magnetic while 316 is non-magnetic, and 416 is also more difficult to weld and machine. Overall, 416 and 316 each have their own advantages and disadvantages, and the choice depends on the specific application requirements.

17-4 Stainless Steel vs. 316

17-4 stainless steel is martensitic stainless steel with higher strength and hardness, making it more suitable for applications requiring good mechanical performance. While 316 stainless steel has slightly lower strength, the addition of molybdenum gives it superior corrosion resistance in chloride-containing environments, and it is therefore more commonly used in marine, medical, and chemical applications where high corrosion resistance is required. However, 316 is also more costly than 17-4. In summary, the two stainless steels have their own advantages and disadvantages, and the choice depends on the specific application requirements.

Stainless Steel Type 304 vs. 316

304 is known for its excellent corrosion resistance and ease of fabrication, commonly used in kitchen equipment and food processing environments. However, 316 offers superior corrosion resistance due to its molybdenum content, making it ideal for marine environments and chemical processing applications.

306 vs. 316 Stainless Steel

304 is known for its excellent corrosion resistance and ease of fabrication, commonly used in kitchen equipment and food processing environments. However, 316 offers superior corrosion resistance due to its molybdenum content, making it ideal for marine environments and chemical processing applications.

314 vs. 316 Stainless Steel

Composition and Heat Resistance:

  • 314 Stainless Steel: Contains higher levels of chromium (24-26%) and nickel (19-22%), and includes 1.5-3% silicon. This composition provides excellent high-temperature oxidation resistance.
  • 316 Stainless Steel: Contains lower chromium (16-18%) and nickel (10-14%), but includes 2-3% molybdenum for enhanced corrosion resistance, particularly against chlorides​ ​.

  • 316L Stainless Steel: Contains a maximum of 0.03% carbon, reducing the risk of carbide precipitation during welding, and making it more suitable for heavy welding applications​.

Applications:

  • 316: Used where high strength and corrosion resistance are needed.
  • 316L: Ideal for welding-heavy applications, such as chemical processing and pharmaceutical equipment​

316Ti Stainless Steel vs. 316

Composition and Heat Resistance:

  • 316Ti Stainless Steel: Similar to 316 but stabilized with titanium to prevent carbide precipitation at high temperatures.
  • 316 Stainless Steel: Contains 2-3% molybdenum for corrosion resistance but is more susceptible to carbide precipitation when exposed to high temperatures for long periods.

Applications:

  • 316Ti: Suitable for high-temperature applications where welding is involved.
  • 316: Used in general corrosion-resistant applications.

321 Stainless Steel vs. 316
