i want to find the yield stress of the steel i am using (a parallel flange channel from corus). all i have from the corus catalogue is that it conforms to bs4: part 1 and bs en 10056:1999.
anytime i do a search on this sort of thing all i get are either lists of standards (but not the actual standards themselves) or else all sorts of different types of grades (i assume grade 300 is a different type of grade to grade 43 and 50).
i have discovered that grades 43 and 50 are both covered by this standard, but they have different yield stresses. should i just assume its grade 43 to be on the safe side? or is ther another grade lower than that also covered?
why o why dont they just put the yield stress of their steel in the book? whats the point of knowing the moment of area if you dont have a clue what the yield stress is?
