yield & allow. stress about chinese standard materials
yield & allow. stress about chinese standard materials
(OP)
Hi
I'm a new member. Anybody could help me? I need a list of yield stress and allowable stress of chinese standard materials, specifically 16MnR, 20, 20R, Q235-A, Q235-B, 30CrMoA, 35CrMoA, and 30CrMo. I have found a web with the chemical composition of these materials, http://www.chinabeitai.com/doce/cp02-2.htm but not the stress values.
Thank you in advance

RE: yield & allow. stress about chinese standard materials
*The A or B suffix may indicate a specific heat treatment, other processing or grade. You probably need the applicable Chinese GB standard (which can be purchased from standards suppliers).

RE: yield & allow. stress about chinese standard materials
I know that the mechanical properties of any material depends on the differents heat treatments (and chemical composition too). About the Chinese GB Standard, I haven't found a copy in english language. I think it is only in chinese language.
EdStainless, these materials are for a chinese code application, not ASME code application.
In any case, thank you both for your help.
P.D.: I'm soory for my awful english
