ASTM A240/ASME SA240 UNS S32750 shim sheets

ASTM A240 UNS S32750 Shims Sheet, Duplex Steel UNS S32750 Shims Sheet, ASME SA240 UNS S32750 Shims Sheet, Duplex Steel 2507 Shims Sheet, UNS S32750 Shim Sheet.

ASTM A240 UNS S32750 shim sheets are the most widely used shim sheets. These sheets are preferable and known for complementing dual microstructure qualities. This grade is made from a mixture of ferritic and austenitic steel, and it has unique characteristics and stand-out properties. 

Duplex Steel UNS S32750 shim sheets provide excellent resistance from various chemical and physical procedures, and it also protects from pitting. ASME SA240 UNS S32750 shim sheets are very malleable and have great strength and flexibility. These sheets are considered an ideal application for various industries and commercial sectors. These shim sheets are significantly this and primarily used for wrapping. 

Duplex S32750 shim sheets are enriched with properties, which is why these sheets are commonly seen in industries with high-temperature applications. This grade has some extreme properties and stand-out characteristics, and it has incredibly high tensile and yield strength. 

Chemical composition: The chemical composition of these shim sheets includes a high amount of chromium. Chromium is an element that provides high heat bearing capacity to the grade, and it also improves the texture of the grade. Similarly, The ASTM A240/ASME SA240 UNS S32750 shim sheets also include a decent amount of nickel, molybdenum, nitrogen, sulfur, silicon, manganese, copper, and phosphorus. These elements are added to provide stability and high heat enduring capacity to the grade.


  • High resistance to chloride stress corrosion cracking
  • Superior resistance to chloride pitting and crevice corrosion
  • Suggested for applications up to 600° F
  • Combination of properties given by austenitic and ferritic structure
  • Good weldability and workability
  • Good general corrosion resistance
