Dual Grade

(OP)
What does it mean "dual grade" as a specification for a material requisition?
My customer want me to use AISI 316/316L Dual Grade...but I didn't perfectly got the meaning. Unfortunately my colleagues too, even the material expert. Could you help me out?
Thank you.
Ciao from Italia!

RE: Dual Grade

In this case the material will meet the more restrictive chemistry of 316L, AND meet he higher mechanical requirements of the straight 316.
