a36 vs a516 plate

Review UCS-6 (ASME Section VIII, Div 1).1Only if it is a vessel for less than 15 psig. SA 36 is of weldable quality. I.e. you can connect it to a vessel. It cannot be pressure containing.Bsly, has this been changed recently? My 2004 edition of S VIII D1 permits SA-36 although with some restrictions on service and thickness. Regards, MikeI believe that SA 36 is quite commonly used for vessel work, although there are some limitations. If thickness is significant, it will generally be more economical to use some other material.Yes, with limitations given in Par. UCS-6. Mauro Gonzagasa36 is the most common in viii-1 for pv constructionGenB: That is scary!I don't know that is the MOST common, but certainly common. If the size and pressure rating of the vessel permit SA36, I imagine most manufacturers would use it. Ditto on atmospheric API tanks. And I don't know why that would be scary.JStephen: Guess I have just seen to many quality problems in the use of a structural steel in a vessel application. Sometimes it will not matter,per UCS-6,but I do not agree that it is most common for vessel application. Cheaper is not always cheapest. I could tell you a number of poor result stories for A-36 but would need a new page. INMHO: Angle,channel,non-pressure,itsOK,but for anything elsebe careful.As an engineer who directly specified or was involved in specifying materials for well over 1000 pressure vessels for use in the petrochemical and power industries, I can only think of one or two which was specifed as being manufactured from SA-36. As an old steel maker, I can attest to the downgrading of many heats of other steels into A-36, which was the "catch all" for downgrades. In the past, the liklihood of laminations in A-36 plate was quite high, and the toughness of the material was especially low in the downgraded heats.1ASTM A1011 vs ASTM A36 - ASTM (testing materials) Code Jul 15, 2009Welding of A-36 and A516 Gr 70 See more results
