1018 Steel Test Specimens, Coupons & Panels

Metaspec makes 1018 steel test specimens, coupons and panels in a wide range of sizes, thicknesses and surface finishes. 1018 steel is also known as AISI 1018 mild or low carbon steel (UNS G10180). This steel alloy is often used in machining and drilling. Some standard test specimen sizes include 1" x 2", 1/2" x 3", 1" x 3", and more. Customized test panels are available on request. 

  • Test panels can be machined from plate or bar material. A wide range of sizes and thickness are available, including panels as thin as 0.032 inch. This process leaves some visible machining marks on the surface instead of an ‘as rolled’ surface finish.

    An additional polishing process can smooth out the machining marks on the faces of the test panel and is available upon request. Machined test panels are interleaved or packed individually to prevent surface scratches.
