Grades and shape

I have the ASTM A500 standard in front of me, and it contradicts many of the statements in this article. There are 4 grades of ASTM A500, not 6, and shape is not a grade. ASTM A500 also allows "special" shapes of tubing, so a list of possible shapes would be infinite. And A500 and A501 are not "used for" structural tubing; they ARE structural tubing. But they are not pipe, however. Please do some research before writing articles. Writing an article about a standard you haven't read is no better than writing an article about a novel you've never read.--Yannick 23:10, 10 October 2006 (UTC)[reply]

I don't have A500 in front of me, but when I was writing it, I did have the standard steel construction manuals in front of me and used those. If the AISC Manual of Steel Construction is wrong, then there's a problem. Most structural engineers don't use the ASTM specs directly, they use the AISC materials. What specifically does the ASTM standard say about the grades? Georgewilliamherbert 23:46, 10 October 2006 (UTC)[reply]

(minor note) - I'm going to fix the phrasing on "used for" per note above. Georgewilliamherbert 23:47, 10 October 2006 (UTC)[reply]

There are four grades, A,B,C and D. Grades A,B,D have the same composition, while C has a bit less carbon. Grade D is heat treated. Shaped structural tubing of grades A,B,C have higher tensile yield strength requirements than round structural tubing of the same grade. Etc. It would not be the first time that an inconsistency was found in a design handbook or standard. Several major piping handbooks state that the pressure rating of a pipe is equal to the pipe schedule divided by 1000 and multiplied by the allowable stress of the material. This is absurdly wrong and terrifyingly dangerous. But it's also widely cited.--Yannick 00:17, 11 October 2006 (UTC)[reply]

I also don't have the spec in front of me, but generally the strength properties vary with increasing plate thickness. Is this the case with A500? —Preceding unsigned comment added by 66.54.184.41 (talk) 16:28, 13 February 2008 (UTC)[reply]
