Stainless Steel Annealing and Pickling Tubing (AP Tubing)

 Introduction

 Annealed and Pickled (AP) tubings with its matt surface,  are commonly used throughout industry  projects   where appearance finishing is not critical.  

The corrosion resistance of stainless steel is mainly due to the reaction of chromium with oxygen to form a dense protective layer on its surface.  During pickling, oil stains and other contaminants on the surface of tubings will be removed to improve the corrosion  resistance of stainless steel tubings.
