ASTM A240 TP316LN Stainless Steel Plate

Key Features of TP316LN Stainless Steel Plate:

High Yield Strength
Compared to standard 316L, TP316LN stainless steel hot rolled plate offers increased yield strength due to the addition of nitrogen, allowing for thinner structural designs without compromising mechanical integrity.

Low Carbon for Weld Integrity
TP316LN stainless steel cold rolled plate contains a low carbon content (≤0.030%), which minimizes the risk of intergranular corrosion after welding. This makes TP316LN ideal for pressure vessels and welded structures exposed to corrosive environments.

Excellent Stress Corrosion Cracking Resistance
TP316LN pressure vessel stainless steel plates exhibit outstanding resistance to stress corrosion cracking in high-chloride and high-stress conditions, making them a preferred material in industries such as nuclear power, oil & gas, and offshore installations.

Suitable for High-Pressure and Hygienic Applications
TP316LN stainless steel plates are commonly used in applications requiring both high mechanical strength and hygienic performance, such as heat exchangers, reactors, pharmaceutical equipment, and food-grade systems.

 What is ASTM A240 TP316LN stainless steel plate used for?
Answer:
TP316LN stainless steel plate is commonly used in industries requiring both high corrosion resistance and mechanical strength, such as chemical processing, marine environments, nuclear power, oil & gas, and pharmaceutical equipment.

What’s the difference between TP316LN and TP316L stainless steel?
Answer:
TP316LN contains added nitrogen, which improves its yield strength and stress corrosion cracking resistance, especially in chloride-rich environments. TP316L has lower strength but is widely used for general corrosion resistance.

What surface finishes are available for TP316LN plates?
Answer:
We offer a variety of finishes including No.1 (hot rolled, annealed & pickled), 2B (cold rolled, smooth), No.4 (brushed), HL (hairline), and mirror finish. Custom polishing is also available.
