Howdy! Im a welder/ everything else metal related. Im trying to improve my skills and would like to find engineering/technical data on structural steel. Generalized, nothing fancy... Standard items like angle, tubes, flat bar, sheet etc. Various size and thickness. Data like, the alloy contents, mechanical properties (load bearing etc) I cant find much online and ive asked the steel shops in my area. They tell me they dont carry data for their steel because it all comes from different manufacturers. I can partially understand that... But it seems the tensile strength (FOR EXAMPLE) of a 5 inch x 2 inch length of 1/8 standard angle from most factories should be very similar no?
