ASME SA240 / ASTM A240 UNS S31635 Stainless Steel Sheet
Leave a message
what is ASTM A240 UNS S31635 Stainless Steel Sheet?
ASME SA240 / ASTM A240 UNS S31635 refers to Type 316Ti (Titanium-stabilized 316) stainless steel sheet, an austenitic grade offering enhanced resistance to intergranular corrosion (IGC) after welding, making it ideal for pressure vessels and high-temperature applications where post-weld heat treatment (PWHT) is difficult, with key benefits including excellent corrosion resistance, high strength, and good fabricability for chemical processing, marine, and furnace parts.
What is the difference between ASTM A240 and ASME SA240?
The only difference is that ASME SA240 is developed and maintained by the American Society of Mechanical Engineers (ASME) and is used primarily for pressure vessel applications. So, while ASTM A240 is used for pressure vessels and general applications, ASME SA240 focuses on the former.
GNEE is a manufacturer that offers plates and sheets in various thicknesses, surface finishes, and shapes. ASTM A240 316Ti steel plates are suitable for highly corrosive pressure vessel applications. Made from chromium or chromium-nickel alloys, these plates can be used in the construction of platforms, tankers, and containers, as cladding materials, and for other purposes. ASME SA240 316Ti grade steel plates are available with various surface finishes, such as 2B, 2D, embossed, or brushed surfaces. Different processing methods are also available, such as hot rolling and cold rolling. Some even have a plastic coating, making them suitable for high-temperature applications such as heaters, condensers, and boilers.

What is the difference between UNS S31635 and UNS S31603?
UNS S31635 (316Ti) is a titanium-stabilized version of 316 stainless steel, while UNS S31603 (316L) is the low-carbon version, with the key difference being titanium addition in S31635 to prevent carbide formation at high temperatures, making it superior for sustained heat and welding, whereas S31603's low carbon content prevents sensitization in ambient/welded conditions, offering similar but not identical corrosion resistance and weldability.
