Product Description

Product Description

 

Introduction

CD6MN (UNS J93371) is casting duplex stainless steel (austenitic/ferritic) in ASTM A995 andASTM A890. The duplex stainless steel alloys offer a combination ofenhanced mechanicalproperties and corrosion resistance.
 

ACI-ASTM CD6MN steel is a duplex stainless steel formulated for casting. Cited properties are appropriate for the normalized and tempered condition. CD6MN is the designation in both the ACI and ASTM systems for this material. ASTM A890 Grade 3A is the ASTM designation. And J93371 is the UNS number.

The graph bars on the material properties cards below compare ACI-ASTM CD6MN steel to: cast duplex stainless steels (top), all iron alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
