steel grade and the carbon rate limit
(OP)
hi,
We use the A283GRC steel grade for our floatting roof construction, and the carbon rate maximum limit is 0.24%, now how determinate the minimum limit, and the standard that explains it, the article that defines.
thankx

the minimum content you talk about and left to the customer how in your opinion the customer can act on it, or if I use the A283 GRC sheet for my floating roof for crude oil, how can I set the limits of the maximum carbon 0.24% which is limited by the but the mini standard? on what basis I accept 0.15% and I refuse 0.14%, there is surely a standard to follow.
thank you.
RE: steel grade and the carbon rate limit
If there is no reason to restrict the carbon content, then don't. All it will do is raise the cost of your material.

please what's or give me a idea about the 1.04 stadandard, i looked on internet but i couldn't inderstand.
weldstan,
I neglected the mechanical properties of the nuance I will try to associate the mechanical data, and see where I can arrive, your logic is very real in addition to that of bob. thanks again
I am going to get started on this subject and I'll hear from you about the results.
RE: steel grade and the carbon rate limit
ASTM standards are compiled into volumes. ASTM A283 is in the volume 1.04. The volume tends to contain standards for similar materials and the testing methods for those materials. You can also purchase the standard on its own. If you are going to be purchasing material to any standard, you need to have that standard and keep updated on the changes to that standard. ASTM publishes a new set each year, you don't always need the new set but if the standards that you are ordering to change you need to know.

You are right about the mechanical characteristics, I said neglect in a sense or I wanted to know the minimum limit following the data cited above which are very close, the result became clear to me, because in such cases we touch directly to mechanical specifications and it will all depend on what we build.

If there is a requirement for lower C content, go for Grade B or A, in that order.
No manufacturer would give you a Grade A plate at the cost of Grade C.
