316LN Stainless Steel Plate Hot Rolled and Forged High-Performance SS Plate

Product Overview

316LN stainless steel is a high-performance, austenitic steel alloy known for its outstanding corrosion resistance, strength, and toughness. This alloy, a low-carbon version of 316 stainless steel, has the added benefit of nitrogen for improved strength and resistance to pitting, crevice corrosion, and stress corrosion cracking. The 316LN stainless steel plate is available in hot-rolled and forged forms, ensuring superior mechanical properties and structural integrity.

316LN stainless steel plates are widely used in various industries such as chemical processing, marine, power generation, aerospace, and petrochemical industries. The combination of excellent corrosion resistance and high strength makes it ideal for applications where high performance is required in extreme conditions.

Key Features and Benefits

• Superior Corrosion Resistance: Exceptional resistance to a wide range of chemicals, including sulfuric acid, phosphoric acid, and seawater.

• High Strength: Due to the nitrogen content, it exhibits greater tensile and yield strength compared to standard 316 stainless steel.

• Stress Corrosion Cracking Resistance: Enhanced resistance to stress corrosion cracking in chloride environments.

• Versatile Applications: Ideal for industries like chemical processing, marine engineering, medical devices, and food processing.

• Temperature Resistance: Retains its strength and stability in high-temperature environments.

Packaging and Shipping

316LN stainless steel plates are packaged and shipped with care to ensure they arrive at their destination without damage. The packaging process includes:

• Protection: Plates are wrapped in plastic film to protect against moisture and dust. They are then carefully placed in wooden or steel crates.

• Marking: Each package is clearly marked with relevant details like grade, dimensions, and certification.

• Shipping: The material is shipped globally via sea, air, or land transport depending on the customer’s location. Sea freight is commonly used for bulk orders.

Shipping Lead Time: 7-14 days depending on the region and order size.

Handling & Storage: To avoid surface damage, it is recommended to store stainless steel plates in a clean, dry, and well-ventilated area. Plates should be stacked flat on pallets, avoiding direct contact with the floor.

FAQ (Frequently Asked Questions)

1. What is the difference between 316L and 316LN stainless steel?

The main difference lies in the nitrogen content. 316LN has added nitrogen which enhances its strength, especially under extreme conditions. This makes it more resistant to stress corrosion cracking and enhances its overall performance compared to standard 316L stainless steel.

2. Can 316LN stainless steel be welded?

Yes, 316LN can be welded. However, it is recommended to use a low-carbon filler material to ensure that no carbide precipitation occurs during the welding process, which can affect corrosion resistance.

3. What is the maximum temperature that 316LN stainless steel can withstand?

316LN stainless steel can withstand temperatures up to 870°C (1600°F) intermittently and 925°C (1700°F) continuously without significant loss of strength.

4. Is 316LN stainless steel magnetic?

316LN stainless steel is non-magnetic in the annealed condition. However, it may become slightly magnetic when cold-worked.

5. How should 316LN stainless steel be cleaned and maintained?

316LN stainless steel is resistant to rust and corrosion, but regular cleaning is essential to maintain its appearance and properties. Use mild soap or detergent, warm water, and a soft cloth to clean the surface. Avoid harsh chemicals or abrasive cleaners.

6. Can 316LN stainless steel be used in cryogenic applications?

Yes, 316LN performs well in cryogenic temperatures and is often used in liquefied natural gas (LNG) storage and transport.

7. What industries typically use 316LN stainless steel plates?

Industries such as chemical processing, marine, aerospace, power generation, medical devices, and food processing often use 316LN stainless steel due to its superior corrosion resistance and high strength.

Conclusion

316LN Stainless Steel Plates are a high-performance material that offers superior strength, corrosion resistance, and versatility for a variety of applications. Whether used in marine, chemical, or medical industries, this material ensures reliability and durability in harsh conditions. With the option of hot-rolled and forged forms, 316LN stainless steel plates meet international standards and are packaged and shipped to provide maximum protection and efficiency.
