Hi I have some formed sheet metal parts (currently using 316 stainless) that have to pass through an oven at 900C. The problem is that they develop a soot on the surface that comes off on the hands when the parts are handled.
Can anyone recommend a material that will remain clean to handle? The part is basically an 8" square sheet (.025" thk) with two large radius90 degree bends in it. It see's almost no stress and does not need to be dimensionally stable.
Thanks in advance for any suggestions, Jon Crouch.
