I have a sheet of SA-414-GI would like to know if it has a fine grain structureThe aluminum content is gt;0.02 from the MTR, which would leave me to believe it has a fine grain structureHowever, if the aluminum was added for deoxidation purposes it may have been added at a different point in the process and have no impact on grain structureOr maybe that doesn't even matter?
Honestly, don't buy a Camaro at 16First off, the ladies don't necessarily look at you more because you have a cool carSecond, you are likely to drive like an idiot in itThird, you are going to pay massive amounts of insuranceFourth, you aren't going to be getting as good of economy out of it as you could with a beast car that costs lessIsn't the LT the V6 Camaro anyway? If so, you are just going to have the real car guys make fun of you because you will more likely than not think you are a bad because you have a CamaroGranted, the new V6 is powerful, but you aren't going to turn heads when it comes to people who know their stuff about carsI highly recommend not buying this car, but if you do, get silver, because any imperfections AND dirt will show up more obviously on black than on silver.
go with the silver ice metallic paint job with black stripes packagethats a hell of a first car, btwgood luck with the ladies!!!.
First, if you want to know whether the grain structure is fine, you can lookSample it and measure the grain size Second, fine grain size is in the eye of the beholder, what are you comparing it to? Third, Al killed steels are deoxidized by adding Al during the melting and casting processIt works because Al is much more reactive with O than Fe is so Al will steal O away from Fe oxides, forming Al2O3 The Al2O3 particles can be very effective at pinning grain boundaries so, if processed approprately, Al can help produce a small grainsizeFor details, consult your friendly neighborhood metallurgist.
