Besides the obvious tensile and yield differences between 80-50 and 90-60 ASTM A148 steel, does anyone know of any other differences between these cast steels? Is 90-60 harder to weld? Is 80-50 less expensive? Anything else I should know so that I can choose the proper cast material for an aggregate crushing application?
