Ground Flat Stock

Show full description

Ground Flat Stock

Ground flat stock at OnlineMetals is a precision-ground, rectangular bar made from high-quality tool, alloy, stainless, or carbon steels, engineered to tight tolerances for flatness, dimension, and surface finish. It’s ideal for applications in tool & die, machining, gauges, or precision parts where consistent thickness and smooth surfaces are essential. OnlineMetals offers a range of grades—such as A2, D2, O1, 4140, and various stainless alloys—cut to size to avoid excess material waste. The stock is surface ground on all four faces, eliminating defects and decarburization, and arrives ready for further machining or finishing. With quick processing and inventory across multiple grades and sizes, it provides an efficient, reliable source for professionals and hobbyists needing precision material.
