Why Choose ASTM A240/ASME SA240 UNS S20161 Stainless Steel Plate?

 

ASTM A240/ASME SA240 UNS S20161, commonly known as 201 stainless steel with molybdenum, is an austenitic stainless steel with 15.0-18.0% chromium, 4.0-6.0% nickel, 4.0-6.0% manganese, and 0.5-2.0% molybdenum. It is designed as a cost-effective alternative to higher-nickel grades like sa 240/a 240 uns s30400, offering improved corrosion resistance over standard 201 grades due to the molybdenum addition, along with good formability and moderate strength. The molybdenum content enhances pitting resistance, making it suitable for applications in mildly corrosive environments, such as appliances, automotive trim, and general-purpose industries.

The ASTM A240/ASME SA240 UNS S20161 stainless steel plate provides better corrosion resistance than sa 240/a 240 uns s20103 and sa 240/a 240 uns s20153 due to its molybdenum content, though it is less weldable than these low-carbon variants. Its affordability and enhanced corrosion resistance make it a preferred choice for applications requiring a balance of performance and cost.

Key benefits of ASTM A240/ASME SA240 UNS S20161 stainless steel plate include:

• Enhanced Corrosion Resistance: Molybdenum (0.5-2.0%) improves pitting resistance compared to sa 240/a 240 uns s20200, suitable for mildly corrosive environments.
• Cost-Effective: Lower nickel content reduces costs compared to sa 240/a 240 uns s31600, making it economical for general-purpose applications.
• Good Formability: High manganese content (4.0-6.0%) ensures excellent formability for deep drawing in appliance manufacturing.
• Moderate Strength: Offers sufficient strength for structural applications, surpassing sa 240/a 240 uns s41000 in corrosion resistance.

Case Study: An appliance manufacturer in India used sa 240/a 240 uns s20161 plates for kitchen equipment, achieving a 20% cost reduction compared to sa 240/a 240 uns s30400 while improving corrosion resistance in mildly corrosive environments.

Corrosion Resistance

 

ASTM A240/ASME SA240 UNS S20161offers enhanced corrosion resistance in mild to moderately corrosive environments due to its 15.0-18.0% chromium and 0.5-2.0% molybdenum content. The molybdenum addition improves pitting and crevice corrosion resistance compared to sa 240/a 240 uns s20103 and sa 240/a 240 uns s20153, making it suitable for applications like kitchen utensils and automotive trim exposed to mild chlorides or moisture. However, it is less resistant to severe chloride-rich environments compared to grades like sa 240/a 240 uns s31603 or sa 240/a 240 uns s32550. For highly aggressive environments, consider sa 240/a 240 uns s20910.

Weldability

 

The ASTM A240/ASME SA240 UNS S20161 has a higher carbon content (≤ 0.15%) compared to low-carbon variants like sa 240/a 240 uns s20103, which may increase the risk of sensitization and intergranular corrosion during welding. However, with proper welding techniques, such as TIG or MIG with low heat input and appropriate filler materials, it can be welded effectively. The molybdenum content enhances corrosion resistance in welded zones, offering an advantage over sa 240/a 240 uns s20200. For applications requiring superior weldability, sa 240/a 240 uns s20153 is a better choice due to its lower carbon content.
