Easy question on ASTM A 36
Easy question on ASTM A 36
(OP)
I am retired and discarded all my ASTM specification books as they were obsolete. Long ago I was on most of the steel (A) committees. Recently someone told me the current ASTM A36 (19) specifies yield as "yield point" not "yield strength" ( offset 0.2 % offset ). I can't believe they would use yield point ; am I getting senile ?

Many high ductility metals (austenitic stainless steel) show no straight portion of a tensile curve.
I don't have -19 handy, but I do have some other steel A specs that are -19 and -20 revs and they all still say 'Yield Strength at 0.2% offset'.

I am tired of asking designers to substitute A516-70 plate for A36 plate.

RE: Easy question on ASTM A 36
A 36 does not cover only plates, but also shapes and bars. ASTM A36 refers to ASTM A6 for a lot of general conditions. ASTM A6 contains a lot of tables for dimensional tolerances, mainly for shapes. If A36 is replaced by a pressure vessel standard then all this is missing.
I do not know the US construction code ASCE. The corresponding European code contains a lot of rules and data concerning fatigue, brittle fracture etc. These data are related to the specific steel grades contained in EN-standards for construction materials. For other materials like pressure vessel steels, you will not find corresponding rules and data and this is therefore an obstacle to the designer of a construction.

Did I mention anything about pressure vessels?
I am well aware that A36 covers a wide variety of forms and that it is still widely used.
The 'general conditions' you mention are the only places A36 is fit for purpose. If the strength were any lower it would make sense to drop tensile requirements altogether. And forget about impact properties for this stuff.
