also, availability of bar stock in various sizes is a consideration. warehouses will not stock a wide range of bar sizes for any single grade of steel, as there is no need. for example, 4340 steel is pratically suitable for any load bearing component on an automobile, but no warehouse will stock it in small diameter sizes, such as for sway bars, as you could accomplish the same thing with a cheaper grade in small diameter bar applications. a warehouse would only carry larger diameter stocks on the higher strength steels. so there's also the cost/quantity factor coming into play. does that make sense? i don't explain things very well.
