Hello all, I need some help with a sheet metal part I am going to produce. The part consists of 12ga A572 grade 50 sheet metal and a 1020 or 1018 steel spacer that will be press fitted into a laser cut hole in the sheet metal. After assembly the part will be powder coated where I know temperatures in the oven are normally 300~400 degrees. Will there be a problem powder coating parts that are pressed together? More specifically I am concerned with there being a difference in expansion rates between the different materials causing the press fit to fail when exposed to those temperatures. I think it should be fine since both materials are low carbon steel and should have similar expansion rates but I wanted to post here for some input/assurance.
