2205 Duplex vs 316 ss Rockwell comparisson
2205 Duplex vs 316 ss Rockwell comparisson
(OP)
I am researching the differences in Rockwell numbers between 316 ss and 2205 Duplex (I am not a metallurgist, so bear with me :) ).
I understand the inherent advantages and disadvantages of 2205 Duplex vs 316 ss (austenite and ferrite structures and what that implies) but the range of Rockwell numbers for 2205 were 31 C (max) but 95 B (max) on 316 ss. I realize the scales are different, so how do I compare the two ratings properly (B and C scales)?
I expect the Rockwell rating to be better on the 2205, but I may be wrong.
Thanks in advance.

Look at your specs, what is the minimum specified strength for the alloys.
In most product forms the minimum required properties are:
alloy UTS yld hardness
316L 70ksi 25ksi RB 90 max
2205 95ksi 70ksi RC30 max
