OBTAINING 4A FINISH IN STAINLESS STEEL TANKS [Michigan] 

July 10, 2008

We are a manufacturer of edm / metalworking filtration systems.
Due to the closure of a tank fabricator who had been providing us with stainless tanks,
we have been encompassed with producing these tanks ourselves. We have an excellent welder, and newer welding equipment; trying to obtain the same "4A" finish is proving to be difficult. We have purchased buffing wheels/pads and a rouge bar, all to no avail.
How can I obtain the same grain finish in the corners (near welds) as is on the front or
sides of these tanks? Do we simply use "Scotch-Brite" type pads in graduating grades?

It would be easier to give you hints if we could see what you want and where you are. Can you send some pictures?
