Duplex

Forgings Round Bars Plates

 

This group of Sainless Steels are called “Duplex” because they have a two-phase microstructure consisting of grains

of ferritic and austenitic stainless steel.

The duplex structure gives this family of stainless steels a combination of attractive properties.

Therefore these types of stainless steels are about twice as strong as regular austenitic or ferritic stainless steels.
