When folding 3042b stainless steel sheet, you will on sheets without plastic coating, mark the material with a line from the outside of the vee. Without using plastic in the vee is there anyway around this on a 3.0mm internal radius, or does the radius need to be increased?
Allowing for the type of mark, and that it is only a visual mark not an indentation you can feel or measure, can these tool marks have any effect on stress fractures occouring in the steel on these lines?

Packie, you need to specify the thickness of the 304-2B sheet! It makes all the difference in the world when discussing bend radii.
