I have a bolt that is HDG and I would like to remove the zinc layer to look at the cracking under the microscope. What is the easiest way to remove this coating without damaging the base metal?
If I receive the same type of steel coils from over 50 different suppliers, but the material is to the same ASTM spec, do I need to make all of these different MSDS sheets available to the public or can I create one consolidated MSDS sheet? Is this legal? If anyone could point me in the right...
I want to do a standard tensile test on a A36 threaded rod (1"-8 threads). I was planning on threading large steel plates to the top and bottom of the rod so that the tensile tester can clamp onto these plates for easier mounting. Is there a way to calculate the minimum thread engagement length...
If I have a rectangular sheet of gauge 12 steel (33 Fy, 45 Fu, 30% elongation), is there an easy way to estimate how many times that I can bend the sheet back and forth (holding the lower half in a vise and bending the upper half back and forth in 180 deg. cycles) before it starts to crack? Is...
Since a 100% brittle material will have no difference between tensile strength and yield strength, would taking the difference between these two values for a ductile metal be a good indication of its ductility? Is there some sort of formula I can use for this?
I have a galvanized zinc rod that is to be bent 20 degrees and I would like to test for the susceptibility for strain-age embrittlement of the final product (since the rod was bent after the hot dip galvanizing process and there will be inherent strain). Since this process will occur naturally...
Is there a relationship between strength and ductility for structural steel? In other words, does the Fu/Fy ratio have any connection to the ductility of a metal? If you take a metal rod with 20% elongation before fracture with a yeild strength of 33 KSI and a tensile strength of 45 KSI, how...
