Why Choose ASTM A240/ASME SA240 UNS S20153 Stainless Steel Plate?

 

ASTM A240/ASME SA240 UNS S20153, commonly known as 201LN stainless steel, is a low-carbon, nitrogen-enhanced austenitic stainless steel with 16.0-17.5% chromium, 4.0-5.0% nickel, 6.4-7.5% manganese, and 0.10-0.25% nitrogen. It is designed as a cost-effective alternative to higher-nickel grades like sa 240/a 240 uns s30400, offering good corrosion resistance in mild environments, excellent formability, and improved strength due to nitrogen addition. The low carbon content (≤ 0.03%) enhances weldability, making it ideal for applications in architectural, appliance, and transportation industries, particularly in low-temperature environments.

The ASTM A240/ASME SA240 UNS S20153 stainless steel plate provides better strength and toughness compared to sa 240/a 240 uns s20103due to its nitrogen content, and it offers improved corrosion resistance over sa 240/a 240 uns s41000. Its affordability and versatility make it a preferred choice for non-aggressive environments.

Key benefits of ASTM A240/ASME SA240 UNS S20153 stainless steel plate include:

• Cost-Effective: Lower nickel content reduces costs compared to sa 240/a 240 uns s31600, making it economical for general-purpose applications.
• Enhanced Strength: Nitrogen addition (0.10-0.25%) improves strength and toughness compared to sa 240/a 240 uns s20103, ideal for structural applications.
• Excellent Formability: High manganese content enhances formability, suitable for deep drawing in appliance manufacturing.
• Improved Weldability: Low carbon content minimizes intergranular corrosion, surpassing sa 240/a 240 uns s20161in welded applications.

Case Study: A transportation equipment manufacturer in India used sa 240/a 240 uns s20153plates for railcar components, achieving a 25% cost reduction compared to sa 240/a 240 uns s30403while maintaining corrosion resistance and strength in mild environments.

Corrosion Resistance

 

ASTM A240/ASME SA240 UNS S20153offers good corrosion resistance in mild environments, such as indoor settings or areas with low humidity and minimal exposure to corrosive agents. Its 16.0-17.5% chromium content forms a protective oxide layer, making it suitable for applications like architectural cladding and transportation components. The nitrogen addition (0.10-0.25%) enhances pitting resistance compared to sa 240/a 240 uns s20103, though it is less resistant to pitting and crevice corrosion than molybdenum-containing grades like sa 240/a 240 uns s31603. For chloride-rich or acidic environments, grades like sa 240/a 240 uns s32550are recommended.

Weldability

 

The low carbon content (≤ 0.03%) of ASTM A240/ASME SA240 UNS S20153 enhances its weldability by reducing the risk of carbide precipitation and intergranular corrosion during welding. This makes it superior to sa 240/a 240 uns s20200for welded structures, as the lower carbon content minimizes sensitization. It can be welded using common techniques such as TIG, MIG, and resistance welding, with appropriate filler materials to maintain corrosion resistance. Compared to sa 240/a 240 uns s20161, UNS S20153 offers improved weldability for applications like railcar manufacturing and structural components.
