ASTM A240 / ASME SA240 UNS S32760 Coil

ASTM A240 UNS S32760 Coil,Zeron® 100 Bar, which is also sold under the names Super Duplex Stainless and Super Duplex, is a highly alloyed stainless steel that is designed for use in difficult and aggressive environments.

The ASTM A240/ ASME SA240 UNS S32760 coils are highly ductile. This grade is considered the most durable grade. The ASTM A240/ ASME SA240 UNS S32760 coils have high malleability and strength. These coils are made of two microstructures, austenitic and ferrite. These two microstructures are known for providing excellent strength and flexibility. 

 ASME SA240 UNS S32760 coils are commonly used for industrial purposes. The grade provides excellent strength to these coils. These ASTM A240 / ASME SA240 UNS S32760 Coils have high demand as they provide excellent services in all types of weather conditions. These coils are enriched with high elasticity and durability. ASTM A240 coils are highly used for various high heat applications.

The thermal expansion of these  Duplex SteelUNS S32760 Coils is between 20°C-400°C.which is why it works in high temperatures. 

Chemical composition:

The chemical composition of ASTM A240 / ASME SA240 UNS S32760 Coils includes a high amount of chromium, nickel, manganese, molybdenum, silicon, phosphorus. The grade consists of a high amount of chromium, 24%, and nickel, 8%. These elements are added to provide stability and efficiency to the grade. 

These coils' tensile and yield strength is exceptionally high, so it is commonly installed in various industries and devices. The high working temperature for these coils is 950°C-1150°C.
