Super Duplex is a super-austentic stainless steel, twice as strong and 4 times as crevice/corrosion resistant as 316L .
We ordered these 2 plates too short and had to order 2 more.
Dimensions are 4"X1/2"X50". Paid $500 for both. This is an exotic material used in the harshest industrial chemical environments, hence ideal for chainplates!! We also have the ASTM certification records.
