Test pieces/ Test specimens/ Test coupons/ Test strips/ Test panels

We provide all kinds of test specimens/ test coupons/ test strips such as microstructure test panels and tensile test panels for welding and thermal spray process qualification.

Test pieces/ test specimens/ test coupons/ test strips/ test panels are manufactured to tight tolerances from bar, sheet, and plate using precision machining methods, which may include laser and CNC.

Our standard test substrates are available for immediate shipment from stock in America and Asia in a variety of sizes and finishes.

Custom panels may also be ordered in a range of shapes, sizes, alloys and finishes including curved, sand-blasted, perforated and pre-painted.

Mechanical Test Specimens

Mechanical test specimens are used to evaluate the physical characteristics of materials. Assessing the strength, ductility, and hardness of an alloy gives the engineer valuable information in determining the best materials for use in industrial applications. Our machines tensile and fracture mechanics test specimens to ASTM specifications or to your requirements.

Specimens in a wide variety of sizes and materials are available.

Corrosion Coupons

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 provide an inexpensive means of on-line monitoring that will allow you to effectively measure the corrosivity within your system. By observing the mils-per-year corrosion rate of an exposed coupon, valuable information can be provided regarding the material’s life expectancy.

We can make coupons in any size, shape, or material you need. Coupons can be stenciled with alloy and sequence numbers for proper identification (ink or laser). Mill test reports, identifying element compositions of materials used, are provided on all orders.

When ordering test coupons, please be ready to provide the sales person with information regarding the type of material you are testing, the style and size of the coupons you require, surface finish desired, and if applicable, mounting hole size and location.
