Introduction to Stainless Steel Coupon

A stainless steel coupon is a small, standardized metal sample used primarily in corrosion monitoring and material testing. Industries such as oil and gas, water treatment, chemical processing, and marine engineering rely on these coupons to assess how stainless steel performs under specific environmental conditions. By exposing the coupon to the same environment as a pipeline, tank, or structural component, engineers can measure corrosion rates, identify material compatibility issues, and make informed maintenance decisions. Stainless steel coupons help ensure equipment longevity, process safety, and regulatory compliance by providing real-world data on material degradation over time.

Stainless Steel Coupon Different Shapes

Stainless steel coupons come in various shapes for testing and analysis purposes.

Rectangular Coupons
First, flat rectangular coupons serve as the most common shape. They allow easy surface preparation and measurement.

Round Coupons
Next, round coupons provide uniform edge exposure during corrosion tests. Researchers often use them in electrochemical studies.

Square Coupons
Then, square coupons offer balanced surface area and edge length. They suit general-purpose testing in labs.

Custom-Shaped Coupons
Finally, custom-shaped coupons meet specific industry needs. Manufacturers design them for unique applications or complex parts.
