Standard Coupon Specs

Accurate monitoring of corrosion rates in any environment is critical when viewed in terms of the maintenance and repair costs associated with corrosion and material failure. Test coupons can provide an inexpensive means of effectively monitoring corrosion levels in a system. By observing the mils-per-year corrosion rate of an exposed coupon, valuable information can be provided regarding the material's life expectancy. The following coupons are commonly used in corrosion testing. Rose Corrosion Services can supply specimens in any size, shape or material you need.

Coupons can be furnished with a variety of finishes depending on your particular application. Some of the typical finishes are defined below.

Mill - finish as produced from mill  

Glass Bead - blasted with fine glass beads to remove mill scale. 

120 Grit - fine finish using a 120 grit belt and commonly used in corrosion tests, such as pitting studies, where smooth surface finish is desired. Finishes up to 800 grit (extremely fine) can be provided by using belt sanders.

Double Disc Ground - extra fine finish using an abrasive disc that leaves minimal residual grit. Excellent for studies where surface finis  is critical. Capable of producing 16-32 RMS finishes on common steels and 8 RMS on carbide steel.
