I feel an argument comming so please just explain your thoughts.I'm pretty sure that stuff is A36. The funny thing about A36 is, as a performance spec and not a composition spec, you can get a batch every now and then that does machine nicely. A36 can have anything in it in any proportion, as long as it meets the strength test requirements.
A36 is an ASTM designation, not a grade, this generally deals with the process used to produce the material as it does with the material itself. There are many grades of steel (formulations) which fall under each ASTM designation. A good example of this is ASTM A29 round bar which can be ASTM A29 Gr.1018 or ASTM A29 Gr.4140, its the chemical make up that controls the grade while the ASTM designation typically dictates the process by which the the steel is produced.
