new duplex grades 5

[mcguire]

There are several lean duplex grades which have some attractive features. 2003, for instance, has the pitting resistance of 317L, high strength, and resistance to SCC.
Their releatively low alloy content makes them less expensive than their equivalent austenitic alloys, in this case 317L.

My question is to users of 316 and 317. Have you considered switching to such a grade? If so, has it worked out well?
If not, what has been the problem? If you haven't considered changing, why not?

I did a quick comparison on 1/4" plate mill plates 96 x 240 on 304L, LDX 2101, 2205, and AL-6XN. We do not sell 2507 so I don't have pricing, but it should be between 2205 and AL-6XN. We also do not sell the 2003 but it should fall somewhere between LDX 2101 and 2205 based on alloy content.

Ratio using 304L as 1.

304L - 1
LDX 2101 - 1.25
2205 - 1.9
AL-6XN - 4.6

Is there a source for small quantities of duplex grade 2205
rod ~3/8 diameter?
