Why Choose ASME SA 240 Gr 316H (S31609) Stainless Steel Sheets?

 

ASME SA 240 Gr 316H (S31609), also known as UNS S31609, is a high-carbon, molybdenum-alloyed austenitic stainless steel designed for enhanced creep resistance and strength at elevated temperatures up to 870°C (1598°F). With 16.0-18.0% chromium, 10.0-14.0% nickel, and 2.0-3.0% molybdenum, it offers excellent corrosion resistance in chloride and acidic environments, making it ideal for chemical processing, power generation, and petrochemical applications.

Key benefits of ASME SA 240 Gr 316H stainless steel sheets include:

• Enhanced High-Temperature Strength: The higher carbon content provides superior creep resistance compared to sa 240 gr 316, perfect for sustained high-temperature environments.
• Excellent Corrosion Resistance: Molybdenum enhances pitting and crevice corrosion resistance, outperforming sa 240 gr 304H in chloride-rich settings.
• Good Weldability: Controlled carbon content minimizes sensitization risks during welding, though sa 240 gr 316L is preferred for heavy welding due to lower carbon.
• Versatility: Suitable for both structural and high-temperature applications, with a durable, aesthetic finish for various uses.
