Apache Stainless Equipment Corporation recently conducted several surface reading studies on the RA smoothness of different stainless steel materials.
In one of the studies, bead blasted finishes were compared to electropolished finishes under 200X magnification. This study as well as RA (roughness average) tests comparing pickle passivated and electropolished materials are included in the white paper co-produced by Apache and Mepaco, Apache’s food processing equipment group.
In the educational white paper, discover: definitions of stainless steel finishes and measurement designations, an overview of stainless steel surface textures, a guide to high-end stainless finishes and RA studies and comparison data. A PDF or printed copy of the paper is available by contacting a Mepaco sales representative or registering at www.mepaco.net/Stainless_Finishes_Sign_Up.
