Alloy 255
Documentation:
CMI Alloy Data Sheet 
Description:
Alloy 255 is a super duplex ferritic-austenitic stainless steel for improved corrosion
resistance. The alloy's high critical pitting temperature and high critical crevice
temperature provide more resistance to pitting and crevice corrosion than lesser alloyed
materials. The alloy's very high yield strength combined with good ductility allows lower
wall thicknesses in process equipment.
