Stainless Steel Price Range In the US 3

[ChihebG]

Experts,

Can anyone provide me the approximative price range(US$/tonne) of the following stainless steel grades in the US :

304L
316L
Lean Duplex 2101
Lean Duplex 2202
Super Duplex 2207

What product form and what quantity?
Of course with the duplex grades you will use much less metal because of the higher strength.
How are you going to correct for that?

I can put them in order:
304L
2101
2202
316L
2507

But you left a few out, 2205 will cost just a little more than 316L but have much higher strength and corrosion resistance.
All of the 20-22 Cr lean duplex grades (<0.5 Mo) are very close in price.

Thanks Ed!
I need to assess the prices for pipes selection ( from 16" to 24") of about 5000 ft.

Yes I forgot 2205.

Large OD pipe, do want it annealed or as welded?
Who in the US is going to make it? (there are only a couple of pipe mill left)

The last time that I ran numbers:
lean duplex grades were 1.05x 304L
2203 was about 1.25x
316L was 1.3x

People may be trying to charge more for the lean duplex because it isn't as common.
Remember if you were going to use 0.500" wall in 3xx you can use 0.375" in duplex, that will save you a ton of money.

Thank for your help Ed
I want welded pipes, I want just to take an order of magnitude of the prices before selecting the supplier as I did not choose him yet.

Run the design in 304L and then in 2101, compare the amount of metal required.
Even though 2101 is a little more per pound I think that you will find it significantly less expensive over all.

Thanks Ed.
Can you give price index of A106 B, 317L and 6 Mo compared to 304L?

Sorry for the weird link, if you don't like it just google "relative alloy cost" and it was my first hit.

Thank you!
I searched a lot but I didn't get it!

317L is only special order, so it needs to be a big job, about 2-2.5x the 304 price.
6%Mo is steep, at least 4x, maybe a little more. But these alloys are strong also so you can use less metal than with 3xx.
And these (like the duplex) really have to be made right, annealing, quenching, and cleaning are critical for corrosion resistance.

I will hazard a guess that 2205 wins because of its uniquity and its great balance of desirable properties.

"If you don't have time to do the job right the first time, when are you going to find time to repair it?"

 

[EdStainless]

If you need that much corrosion resistance, if not then a lean duplex will win.
The lean duplexes are only a little more expensive per pound than 304, so factor in the strength and it is a deal.
