A276 Type 316 Condition B
A276 Type 316 Condition B
(OP)
Is A276 Type 316 Condition B a stainless steel that is produced/used much? I have called this out in a calculation and then come to find that our local stainless distributor does not stock it and has never heard of it being requested.
Does anybody stock it?
I was trying to avoid the more expensive A564 Type 630 Condition H1150...but I don't even know if this is more expensive, because I can't get a quote on the A276 Type 316 Condition B.
Thanks for any help !!

As cold worked material is common in tubing, but not so much in bar.
You aren't going to tensile load this part are you? Is there any chance that it could ever be exposed to salts or chlorides? Cold worked austenitic SS is very sensitive to chloride stress cracking.
If tensile load is the application Why don't you look at either a ferritic SS, duplex SS or a PH grade.

I will be posing this following question to some vendors...but, didn't know if anybody had some insight into it...
What is the corrosive resistance difference between ASTM A564 Type 630 Condition H1150 versus ASTM A276 Grade 316 Condition A ??
It now appears that there really is no cost difference, and since the mechanical properties are so much better for the A564 Type 630 Condition H1150 - it seems to be a 'no brainer' to start calling that out in the Calculations/Bill of materials.
Thanks !

If you don't need all of hte strength I have two other possabilities for you.
First, look at the 1150M overaged condition, the toughness is much better.
Or, if you don't need quite as much strength and want more corrosion resistance look back at A276 and alloy S32205 (duplex).

Bar 316 SS or any stainless is hard to cold work over
1 1/2" dia, I like to use 1 1/8" max. You can get 316 SS Bar up to the 1 1/2" dia by getting your fastener supplier to get the bar stock used for A193 B8 Cl 2 fasteners.
Come back with the product form you need.

My question about using 630 in the H1150 condition, do you have a requirement to use the material in that condition? Or are you getting this in that condition for machinability?

If you can pay the premium you might wnat to try sandvik, I know they have a new PH stainless alloy (they call it Nanoflex) that has less Cr than the 17-x alloys but also includes ~4%Mo and ~9%Ni. I know that it's available in sheet form from .015mm to 2mm thick, I dont know about bar or shaft stock.
