This Firechrome Oversize Tolerance Ground Flat Stock is made by Precision Marshall Steel Company. The steel type is AISI H-13 hot-work tool steel, annealed to 21 Rc (230 Brinell). It has an exceptionally fine structure resulting in improved machinability, polishability and high temperature tensile strength. Applications include hot-work tools, die casting molds, extrusion tools, forging dies, hot shear blades, stamping dies, and plastic injection mold details.

The standard nominal sizes are ground to a satin finish on four sides, free of decarburization, held to tight tolerances in dimensions and squareness, and ready for layout. Each piece is lightly coated with rust-preventive oil and individually packaged in a vapor-resistant envelope which has the size and steel type clearly marked. At least one end is painted brown for easier identification of the steel type.

The oversize Thickness |T| tolerance is +.010/+.015". The oversize Width |W| tolerance is +.010/+.015". The Length |L| tolerance is +.188/.375".

The available thicknesses are 1/4 to 1 inches. The available widths are 1 to 4 inches. Please contact us if you need a different size, or if you need us to make any alterations.
